Hi! I'm the author of this check. Could you please share larger snippet of your code around this crush (what templates class has, where mutex is stored, etc..)? I failed to reproduce this on trunk in godbolt: https://godbolt.org/z/rnsbs5fdE.
I will try godbolt snippet with exactly 21.1.0 later, maybe some patch fixed it already.

[vbvictor]

It would be very helpful if you could modify https://godbolt.org/z/rnsbs5fdE to get the crush and share link with me.

[PhilippGuertlerKeen]

Sorry, I can't reproduce it on godbolt either, even if I paste the entire code of my file.
It is however occuring reliably if I feed in my cmake build directory to run-clang-tidy at that exact location "MyOtherFile.h:63", whenever that file is imported by another one.

[EugeneZelenko]

Could you share preprocessed file (clang -E) if code in question is not proprietary? If you could not share, you could try to use creduce on preprocessed file to create reproducer. But I was not fortunate myself to build creduce with more or less recent LLVM :-(

[PhilippGuertlerKeen]

Sadly the code is proprietary.
I tried reducing it with creduce, but that program crashes on me sadly aswell.
I can confirm however, that clang-tidy from LLVM version 20.1.8 does not crash on this file, while the clang-tidy from LLVM version 21.1.0 does.

I'll try my best to come up with a minimal example, but that might take a while.

[vbvictor]

I can confirm however, that clang-tidy from LLVM version 20.1.8 does not crash on this file, while the clang-tidy from LLVM version 21.1.0 does.

The check was added in 21th version so 20th naturally don't crush

[PhilippGuertlerKeen]

Even though it is not reproducible on godbolt, I have a minimal code setup here that reproduces the crash reliably in my project: https://godbolt.org/z/h4o1j8Kfr
A few more insights:

• The crash does not occur if I call clang-tidy "Example.h"
• The crash does occur, if I call clang-tidy -p=path/to/my/cmake/build/directory "Example.h"`
• We use clang-tidy for static code analysis, but the build toolchain is actually gcc12 (not sure if that's an issue, I guess it shouldn't be). The compile-command for the file in question in compile_commands.json looks something like this: /somebins/bin/aarch64-linux-gnu-g++ --sysroot=/somebins/aarch64-linux-gnu/sysroot -I/project-path/source/my-project/src -I/project-path/source/my-project/test -I/project-path/source/my-project/include -I/project-path/cmake-build/Debug/source/my-project/my-project-json -I/project-path/cmake-build/Debug/source/my-project/generated -isystem /somelibs/include/ -g -std=gnu++20 -fPIE -pipe -Wall -Wextra -Wformat=2 -Wold-style-cast -Wno-unknown-pragmas -Wno-reorder -Wno-unused-parameter -Wno-unused-value -Wno-overloaded-virtual -Wno-missing-braces -Wnull-dereference -Wdouble-promotion -Wmisleading-indentation -Wduplicated-cond -Wduplicated-branches -Wimplicit-fallthrough=5 -Werror=return-type -Werror=non-virtual-dtor -Werror=delete-non-virtual-dtor -Werror=old-style-cast -Werror=implicit-fallthrough -Werror=misleading-indentation -Winvalid-pch -include /project-path/cmake-build/Debug/source/my-project/CMakeFiles/my-project-test.dir/cmake_pch.hxx -o CMakeFiles/my-project-test.dir/test/MyFile.cpp.o -c /project-path/source/my-project/test/MyFile.cpp - the actual file that errors is a header file which gets included from MyFile.cpp

[EugeneZelenko]

Clang-Tidy may assume C as language when you run first scenario. In second case it should properly set C++20.

Could you try to run Clang-Tidy using different version of GCC? libstdc++ version may affect Clang-Tidy.

Other experiment - to use libc++.

To do these experiments you need to tweak compile_commands.json.

[vbvictor]

Another helpful thing would be to install llvm-symbolizer to get accurate crush backtrace

If I use llvm-symbolizer, I get this backtrace here:

@vbvictor Does the call stack of the crash help you?
