Thank you for verifying. Do you test with clang-20 and if so, are tests
at that same revision passing? I want to make sure this is an LLVM
regression before trying to get into figuring out how to bisect with
your setup. Another way to do that is to see if clang-nightly boots are
failing on the stable branches, which would point to Linux not being at
fault.

Cheers,
