clangd Segmentation fault in StaticAccessedThroughInstanceCheck

[dennisoberg]

Indexing TomHandler.cpp crashes clangd. The issue can be reproduced with the command below. Can this be resolved ? Is there a workaround ?

Since the crash is occurring inside the implementation of a clang-tidy check, you should be able to work around it by disabling this particular check, e.g. by adding the following to your .clangd config file:

Diagnostics:
  ClangTidy:
    Remove: readability-static-accessed-through-instance

To investigate the crash further, we would need example source code that triggers it.

It would also be interesting to know if a standalone clang-tidy run (with this check enabled) triggers the crash.

[dennisoberg]

Ok great. I will try that. I have another crash that is not clang-tidy. I create another report for that.

[dennisoberg]

When disabling readability-static-accessed-through-instance it does not crash due to clang-tidy anymore but then the other bug reported happens instead. https://github.com/clangd/clangd/issues/1130

[dennisoberg]

Only clang-tidy does not crash. See attached file.
