On all OS X versions. The only difference is that in OS X 10.9 the system library changed from libstdc++ to libc++. However, Apple's libstdc++ is not identical to libgcc's libstdc++, so yes, mixing libgcc's and the system's libraries can cause problems on any version of OS X. >> The FSF GCC ports each used to include their own runtime and support >> libraries (libstdc++, libgcc_s, etc.).
