> Would it be possible to fix this issue quickly, if not can you revert this patch?

As @xbolva00 mentioned, if you're sure your code doesn't have UB, you can revert my commit first.
Can you provide libc++ related commits? Only 564ed0b <https://github.com/llvm-premerge-tests/llvm-project/commit/564ed0bd2245d4477dfd1c2f610294eff697edab>?
I can investigate tomorrow when I wake up.
