I have tried with clang/llvm (10.0.1) without luck to reproduce.

I think this is a part of the long (recent) discussion about clang

12.0.0 != 10.0.1
Yes, I have noticed that.
11.0.0 is at rc2, 12.0.0 is only in master w/o tag.
I _could_ install sys-devel/clang-12.0.0.9999 locally, after all it
would go to different slot, but I would rather not.

Right, is there anything I could do or are we going to have similar mail
