Extended Description

Clang keeps crashing and told me to file a bug report. I am using emscripten and c++ modules and was trying to compile some of the code from this repository: https://github.com/justinhj/astar-algorithm-cpp

I am unfamiliar with the inner workings of LLVM, but I am happy to compile a debug build or something if it helps.

clang version 14.0.0 (https://github.com/llvm/llvm-project 78e87970af888bbbd5652c31f3a8454e8e9dd5b8)
