Could you please try 20 or main branch?

Jun 19 '25 11:06 zwuis

will do, I will need to spin up a new container, rebuild the dependencies etc will take the computer a little while to turn the cogs then I will get back to you

Jun 19 '25 11:06 tonygould

It took a while to upgrade my whole project... Strangely, multiple build of the file that had failed before now succeed (5 in a row, which is inconsistent with the hypothesis that clang-tidy 20 fails on this translation unit). OTOH, I see crashes elsewhere in the code base.

For example, e.g. on a single file which is simply #include <boost/redis/src.hpp>. I get the below. As you can tell, this is simply including the boost redis src file that is necessary to link to boost redis.

Apologies, it has taken me a lot longer than expected to upgrade + get something building, and not sure I can spend a lot more time on this. I appreciate the effort that has gone into clang-tidy, and apologies in advance if I can't spend more time on this, but I hope that the stack traces might help improved the tool.

I tried locally on commit 74687180dde07312521db09c6f6454fe9d1e5662, and It didn't crash.

// gh144862.cpp
#include <boost/redis/src.hpp>

int main() {}

./bin/clang-tidy --checks=-*,misc-unused-using-decls gh144862.cpp

I couldn't find any related commits of fixing this crash in misc-unused-using-decls using git log. There were a couple of commits improving performance, maybe it was fixed somewhere there.

Oh, I could get the crush on "bugprone-crtp-constructor-accessibility" but it seems you have this rule disabled. Commit 74687180dde07312521db09c6f6454fe9d1e5662, file:

#include "boost/redis/src.hpp" // 1.88

int main() {}

hey thanks for all the investigation!

As I said, I'm up against it now on some hard-deadlines at work but my sense having built on different clang /clang-tidy versions is that's there's an underlying bug which reveals itself in different circumstances, possibly a "Heisenbug" (I hate the term, sorry, but you know what I mean). In the original report I saw multiple different kinds of backtraces. Then I didn't see the error on clang-tidy-20 but I did see it on the different file where I include boost/redis/src.hpp. I've also seen crashes in vanilla clang on various compiles -- but I'm trying to get my day job done so if I can rebuild and it works, I tend to move on. Thanks again.

Jun 20 '25 17:06 tonygould

Btw I'm liking that clang-tidy 20 is picking up new stuff, e.g. spotting auto should be const auto& in contexts such as lambdas which it didn't before. This is a huge benefit of clang-tidy in my opinion, spotting performance issues where it's easy for me or a colleague to forget an ampersand here or there :)

Jun 20 '25 17:06 tonygould

there's an underlying bug which reveals itself in different circumstances

I've seen an issue about a Heisenbug, though no work was done because of lack of reproduces, I guess.

It would be great if you could make a debug build of clang-tidy from main branch and use it for some time in your project to see if it crashes or not (when you would have free time, of course). If it crashed - we could potentially see an assertion.

Jun 20 '25 18:06 vbvictor

I have just two weeks left in my current job, but so far as I am able I will help. Is there an idiot's guide as to how I can build clang-tidy debug? This issue has given me a kick to upgrade our build system to ubuntu 25.04 / gcc14 / clang20.

Jun 20 '25 18:06 tonygould

You could follow these steps assuming you have ninja:

Run configure in llvm-project directory, adjust defines for your system:

cmake -DCMAKE_BUILD_TYPE:STRING=Debug -DCMAKE_EXPORT_COMPILE_COMMANDS:BOOL=TRUE -DCMAKE_C_COMPILER:FILEPATH=/usr/bin/clang -DCMAKE_CXX_COMPILER:FILEPATH=/usr/bin/clang++ -DCMAKE_BUILD_TYPE=Debug -DCMAKE_CXX_FLAGS=-g -DLLVM_ENABLE_ASSERTIONS=ON "-DLLVM_ENABLE_PROJECTS='clang;clang-tools-extra'" -DLLVM_USE_LINKER=lld -DLLVM_PARALLEL_COMPILE_JOBS=24 -DLLVM_PARALLEL_LINK_JOBS=24 -DLLVM_PARALLEL_TABLEGEN_JOBS=24 -DLLVM_TARGETS_TO_BUILD='X86' -S llvm -B build -G Ninja

Build:

cmake --build build --config Debug --target clang-tidy

Jun 20 '25 18:06 vbvictor

After that, you could use -clang-tidy-binary flag in run-clang-tidy.py to specify freshly build clang-tidy. I can't recommend any cmake install commands since I haven't tested it myself, but they can be found in https://llvm.org/docs/GettingStarted.html

Jun 20 '25 18:06 vbvictor

Thank you! My project is building -- an order of magnitude slower :') -- will let you know if I see any issues. (Your build instructions worked perfectly, and to install I simply replaced the link /usr/bin/clang-tidy with a link to the one I'd built.)

Jun 23 '25 10:06 tonygould

(I just picked the latest llvm commit, which happens to be the below, hope ok commit 4af96a9d83335b3b59f3441af47c879c7a9eb183 (grafted, HEAD -> main) Author: Momchil Velikov [email protected] Date: Mon Jun 23 09:28:33 2025 +0100)

Jun 23 '25 10:06 tonygould

@vbvictor have done several complete rebuilds using clang-tidy. This version from yesterday seems remarkably stable compared to previous ones. I wonder, is it worth me trying a sanitize build if it's possible to build that? I've found with our own code bases that certain intermittent crashes are most likely to show up and give a back trace from a crash in a sanitize build. If so, how would I modify the build instructions in your post above to get a sanitize build?

Jun 24 '25 12:06 tonygould

how would I modify the build instructions in your post above to get a sanitize build?

You can specific CMAKE variable LLVM_USE_SANITIZER. See https://llvm.org/docs/CMake.html.

As odd as it sounds, but these memory leaks may be intentional, please see #143129

Actually, it is unproductive to have to keep switching clang-tidy whenever I hit the file that is associated with this arena allocation. Maybe I'm missing something, but as it stands I can't run my sanitized clang-tidy over my whole project.

Just to check, what options would be useful for clang-tidy sanitizer? From https://llvm.org/docs/CMake.html.

LLVM_USE_SANITIZER:STRING Define the sanitizer used to build LLVM binaries and tests. Possible values are Address, Memory, MemoryWithOrigins, Undefined, Thread, DataFlow, and Address;Undefined. Defaults to empty string.

I currently have Address;Undefined. I was under the impression that in general, I can separate address and leak sanitizers, but I don't see that option here. In any case, happy to build with anything you might recommend as useful in tracking down the failures I have been seeing (or showing they don't occur in the latest clang-tidy src).

Jun 25 '25 15:06 tonygould

Given that this is a crash, could you reduce the input? At some point the code should be so small that it would not contain any proprietary code anymore. You can use creduce or it's faster sibling cvise and to ensure the flakyness does not mean the wrong thing is reduced, maybe just repeat the clang-tidy call 15 times or so in the interestingness script? So copy the compile command from the compile-commands.json and then run clang-tidy a few times in the interestingness test.

(A preprocessed input is best but might not work)

Jun 25 '25 20:06 5chmidti

Following code causes a crash pretty reliably using release build of latest clang-tidy, but it feels like a different kind of crash from that I see elsewhere (and also this is the file that has the arena leaks so can't use sanitizer)

Is there anything more I can do on this issue? (I will shortly be unable to do more)

In summary, building with debug asserts didn't show anything, sanitizers did, and there's a minimal reproducible example in the post above , using publicly available includes.

It would be super helpful if you were able to reduce the bug down to just the code needed to cause the crash without any includes. Each include brings in a ton of extra source code which is often entirely unrelated to the crash but complicates our ability to step through the logic in a debugger to get to the root cause of the issue. Removing the includes and getting it down to just the bit of code that's tripping up the compiler can save us a ton of time. (There are tools which can help with this, like creduce, but it can still be a bit of a slog so it's fine if you're not able to reduce the issue further.)

Beyond the lib versions of the libraries included, I don't think there is more you can help with within the short amount of time. You've already provided reproducer snippets, thanks for narrowing things down so far, so to look into this we just need to experiment a bit to reproduce this. The backtraces help with narrowing things down (could be an assumption in the matchers is broken? But then it shouldn't be so flaky...).

OK, I'm not sure I can cut down the code beyond the includes. The complexity of the includes are intrinsic to the crashes, I think. But I'll see if I can reduce the number of includes. It's a combinatorial problem, obviously, but we do include nlohmann json in other translation units so it may be that this is independent of the issue and can be removed.

Related, is https://github.com/llvm/llvm-project/pull/128150. I know strictly speaking it's working around the problem that is buried in 100s of ks of boost code included in my translation unit, but if we could turn matchers off for system header files somehow, it would not only have a hugely positive impact on integrating clang-tidy with medium to large projects, it would also likely make stability issues of the kind I'm seeing go from 2-3 sigma to 3-4 sigma frequency. Is there any way I can turn on @carlosgalvezp 's changes on latest llvm code that I'm building and see if it fixes the stability issues I'm seeing?
