Hello,

A bothering issue with LLVM / clang 14 which prevented to use C++ coroutines with the undefined behaviour sanitizer was fixed recently:

https://github.com/llvm/llvm-project/issues/49689

The patch:

https://github.com/llvm/llvm-project/commit/6678f8e505b19069a9dbdc3e3ee088d543752412

Since there won't be a new patch release of Clang / LLVM past 14.0.6 according to https://discourse.llvm.org/t/llvm-14-0-6-release/63431, would it be possible to apply this patch locally on Arch ?

thanks
This task depends upon
