I’d say the latter. Whereas mixing libc++ and libstdc++ fails at compiling already, miking Apple’s old libstdc++ and gcc48’s new libstdc++ may work, or it may cause crashes; if the latter, that’s just the way it is.

Personally, I feel that the cleanest solution is that C++11 code requires OS X 10.9 or later, unfortunately.
