This likely belongs upstream (if it's even worth fixing at all), but just filing here for now since it's always in neovim that I see these, and I'm sure at least some diagnosing of what the backtrace in there is saying will be helpful before doing so.
How do you enable core dumps?
My lean-language-server crashes very often when editing Lean 3 buffers. I am on neither macOS or using an ARM CPU.
It depends a bit on your distro -- you can typically run ulimit -c unlimited in the shell (before starting neovim) to enable them for that shell session, and then they'll either be written out to your working directory or to somewhere in /var
Here is the crash dump backtrace. I havent used gdb before so I am unsure if there is anything else I can run to give more info.

Interesting. That indeed seems to be crashing in a similar spot to my layman's eyes. I tried staring at how lean::sexpr::get_int() could end up getting called with a null pointer a few weeks back and didn't manage to see how it was happening -- if you're on linux and can get this to happen you have more fun toys (like reverse debuggers) which may make it easier to tell. @gebner not sure if there's anything obvious to you from the backtrace? But yeah if this happens often for you as well maybe we should indeed take it to the upstream lean(3) repo.

I am on linux but I have not used a reverse debugger before. Would a full backtrace with debug symbols be useful, you think? If so, Ill try to submit a bug report to the lean repo.
I am on linux but I have not used a reverse debugger before.
(I'm no expert clearly either, but yeah something like rr is somewhat easier for non C++ programmers to poke back and forth at.)
Would a full backtrace with debug symbols be useful, you think?
I think all the important symbols that that would get are already there, so I think not, but not 100% sure -- much more helpful would be if you know how to deterministically get the crash to happen. For me it's not deterministic, so I literally wrote a neovim function that randomly moves the cursor until it happens.
If you can, building with release type Debug is certainly helpful. This will also enable extra assertions (and hopefully point to the actual source of the error). Maybe you could also change this line in format.h (which looks like the only place that could construct an invalid format object):
explicit format(sexpr const & v):m_value(v) { sexpr_kind(v); }
Maybe you could also change this line in
format.h(which looks like the only place that could construct an invalid format object):explicit format(sexpr const & v):m_value(v) { sexpr_kind(v); }
Do you mean I should change the line linked below to the snippet you posted? https://github.com/leanprover-community/lean/blob/65ad4ffdb3abac75be748554e3cbe990fb1c6500/src/util/sexpr/format.h#L155
I am unable to reproduce the seg faults after changing the line @gebner proposed and building with release type Debug. Was the line change meant to fix the issue?
No the change was supposed to make Lean crash faster. Can you try again with the Release build type?
Here's a SIGABRT from a Debug build:

EDIT: OK enabling ASAN on all my leans, let's see if that helps...
I've just developed a strong hunch that this has to do with our handling of pin updating in the on_lines callback (i.e. my fault...), as I've only ever seen this while editing. I think we may be doing things out of order somewhere in a way that the server doesn't expect. Not sure if that's enough of a lead for either of you, but I promise I'll start getting up to speed with this repo and work on fixing this within the next few days.
^ one way to test this theory would be to pause/disable infoview updates whenever you start editing and only re-enable them once you're done, and see if you ever get a segfault doing this. I'm doing more reading than writing at the moment but lmk if someone else has the chance to daily-drive this.
Thanks for the idea! I think part of the thing that makes this annoying is it's really random to reproduce. Every few weeks it will happen 50 times in a row in a 20 minute period, and then other times only once or twice a day, and I have no idea why...
I want to say you're right that it mostly happens when editing though, which is extra annoying because usually that means I've finally gotten a minute to do some Lean and it's hard to context switch to learning how to C++ debug...
But I'm pretty confident we'll figure it out eventually.
On the above -- I gutted infoview.__update_pin_positions to do nothing locally, and still see sigabrts :/.
It's dealloc_cons that always aborts here, and there's a catch there trying to catch bad allocations I see, but my C++ isn't good enough to know whether that catch block is meant to handle this double-free or just failed mallocs. Alternatively I want to try maybe making lean::server::info, which seems to be what calls that, sit behind a mutex and only handle one request at a time possibly? But my C++ is really horrid, so if either of the two of those sound obviously wrong, let me know.
Darn, yeah if #260 is related then I still see the problem in Lean 4 with the pin window paused. So it could be an upstream issue independent of incremental vs full document sync? Though from the sound of it none of you have seen this problem in Lean 4, so maybe something's off on my end.
Also facing this issue. My main problem is that lean.nvim does not handle it well, and I wind up having to restart neovim completely for it to work again (sometimes doing :LspStart after the segfault works, but not always). I would appreciate some way to force reload lean.nvim as a workaround for this issue until it can be fixed.
EDIT: :LspStart seems to always respawn the LSP properly (:LspInfo says that it's running), but lean.nvim doesn't seem to properly detect that and the infoview doesn't update correctly.
