--- Comment #9 from Igor Kushnir <igor...@gmail.com> ---
Got another crash while completing an include. This time the first thread
crashed and its backtrace matches the more common one in this and duplicate bug

Found a single similar backtrace in an existing bug report:
https://github.com/llvm/llvm-project/issues/25216. The backtrace is reasonably
close given the 8.5 year gap, but the crash is very old indeed. The LLVM issue
description states that reverting a 9.5 year old commit works around the crash.
Can anyone try to revert it and see if the crash disappears?
