I was trying to check the following code:
[BugRepro.zip](https://github.com/user-attachments/files/16950199/BugRepro.zip)
with clang-tidy version from [LLVM 18.1.8-win64.exe](https://github.com/llvm/llvm-project/releases/download/llvmorg-18.1.8/LLVM-18.1.8-win64.exe) and it crashed with the following trace:
```
