FWIW I think I just hit this when building llvm itself (though 15.0.6) with a
recent clang, and getting:

I didn't managed to fully bisect it yet, but it looks very much like
924701311aa79180e86ad8ce43d253f27d25ec7d for this issue is the culprit.
So has that now been reverted, and is the reversal also merged into the 18.x
release branch?
