Segmentation fault when slicing cxxfilt in binutils-2.34

[yangke]

Hi, llvm-slicer (master branch of dg: bf49092) crashed when I analyze the llvm byte code of cxxfilt in binutils-2.34. The slicing criteria 'is_legacy_prefixed_hash' is a call site in 'rust_demangle_callback' in rust_demangle.c Any suggestions to solve it?

Uploading cxxfilt.0.0.preopt.zip…

[mchalupa]

Could you compile DG with -g -fsanitize=address,undefined and post the output of running the llvm-slicer after that?

P.S. the link for cxxfilt.0.0.preopt.zip seems to point to this issue, not to an archive.

[vwvw]

I get the same issue with another porgam. It seems to be related to a recursive call in ReadWriteGraphBuilder.

Here's the output with the sanitizers flags.

Let me know if I can provide you with something more! Thanks in advance for the help

[mchalupa]

Thanks for the output.

It seems to be related to a recursive call in ReadWriteGraphBuilder.

Yes, the problem is too deep recursion. I have a suspicion that the program contains a cyclic re-allocation of memory using realloc which leads to cycling infinitely (well, until the crash) in the builder.

[mchalupa]

Could you post here/send me a link to the bitcodes that trigger this issue (the link above is still not working). Thanks!

[vwvw]

Here the .bc file. optipng-lib.bc.zip

In the mean time, I'm trying to run llvm-slicer from this commit. It's the one just before some changes to ReadWriteGraphBuilder. Until now, it didn't crash... I'll update you when I get some results.

Sorry for the late reply. Here is part of the output of DG compiled with -g -fsanitize=address,undefined

[mchalupa]

These are "only" leaks, the log does not show any crash. So the crash is not present anymore? What was the version of DG that you used? Was it the one before the changes (https://github.com/mchalupa/dg/commit/d1ac57f988c62cdff06f8d321573eea961854839) or after them?

[vwvw]

Yes, I still get a Segfault.

Here for example on who.c from coreutils. I compile it with gllvm and get the .bc file via the get-bc command they provide. The provided .bc is valid but I'm not able to parse it via dg.

[8759s]

I have the same issue with stat program in coreutils. I used wllvm to compile and extract the bitcode.

[yangke]

or after them?

The used version is after d1ac57f, the segfault still exists in the latest version of DG.

[mchalupa]

Do the commit 7692458 fixes the issue for you?

[yangke]

Do the commit 7692458 fixes the issue for you?

This problem still exists in the latest master bf3dc26. It seems that recursive call between these functions is not properly terminated
