    The project sometimes builds and sometimes fails to build with the below backtrace

I'm not sure what other information to give here, other than the backtrace - please let me know what (if any) other information would be useful to include and I will try my best to return with that information 🙇 

```
0:12.22 PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace.
