LLVM currently fails to build with GCC 6 (see openSUSE:Factory:Staging:Gcc6):

This looks like a clang bug to me (note how we use clang++ in the above.

Thanks for the heads up, I'll report it upstream.

Why again don't we use libc++ with clang? ...

We could do that but that means anything that links to llvm will have a libc++ dependency, and not sure how it would end up when you link libc++ and libstdc++ in the same program. -- You are receiving this mail because: You are on the CC list for the bug.
