I recall a recent discussion explaining why/how C++11 support in clang 3.4 was less complete than in GCC. In any case I can't get kdevplatform and kdevelop to build with clang 3.4 on OS X 10.6.8 (on 10.9 it works fine), but gcc 4.8 and 4.9 have no issues.

Also, I don't think there's a C++ runtime issue on 10.6.8 (or rather, it's the opposite; using libc++ is neigh impossible).
