This occured on lix's ci (logs: https://buildkite.com/lix-project/lix/builds/6938/steps/canvas?sid=019b034f-0320-4bac-8f9f-b8d162e47e87 )
The `lix-charptrcast` check is at https://git.lix.systems/lix-project/lix/src/branch/main/subprojects/lix-clang-tidy/CharPtrCast.cc
This crash happens quite reliably over various versions of llvm, in this case it is with 21.1.7
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace.
