If I switch to the "normal" clang Compiler in Xcode it works. If I switch from using "libc++" to "libstdc++" it also works, its the combination of the current clang and libc++ that have this problem.

This is looking like a clang problem. I've got TOT libc++, but a slightly older clang and I'm not seeing this behavior.
