I've tried new feature of C++ 20 with llvm18. When i'm trying to build my pet project build is crashed
I've created test repository where this error occured: [https://github.com/Kawaiilodon/clang-fatal-build/tree/master](https://github.com/Kawaiilodon/clang-fatal-build/tree/master)
I'm building my project in docker with Ubuntu 24.04.1 LTS
