I've tried new feature of C++ 20 with llvm18. When i'm building my pet project build is crashed
I've created test repository where this error occured: https://github.com/Kawaiilodon/clang-fatal-build/tree/master

I'm building my project in docker with Ubuntu 24.04.1 LTS
LLVM is from Ubuntu repository. I've attached files that needed for diagnostics in the end of this issue

cmake -Bbuild -GNinja
ninja -C build
