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, Nathan
