I just tried building clang 3.8.0 with gcc 5.3.0, but that went fine. However, by default gcc uses its own copy of libstdc++. The above error is most likely something caused by libc++ and gcc not playing well together. This kind of error is always hard to report upstream, since the gcc maintainers obviously do not care that much about libc++, while the libc++ maintainers do not care that much about gcc. :-) -Dimitry
