An ABI incompatibility crept into the libc++ 3.4 import in r261283. It
was caused by upstream libc++ commit r194536, which aimed to make the headers more standards-compliant, by making std::pair's copy constructor trivial. Unfortunately, this could cause certain C++ applications using shared libraries built against the previous version of libc++ to crash. Fix the ABI incompatibility by making std::pair's copy constructor non-trivial again. Please note: Any C++ applications or shared libraries built with libc++ between r261283 and this revision should be recompiled. Reported by: stefanf MFC after: 3 weeks X-MFC-With: r261283
