I don't understand this code:

 _LIBCPP_NEW_DELETE_VIS void* operator new(std::size_t __sz)
 #if !__has_feature(cxx_noexcept)
+#if defined(_LIBCPP_MSVC)
+    throw(...)
+#else
     throw(std::bad_alloc)
 #endif
+#endif
 ;

Are you anticipating that operator new will throw things other than std::bad_alloc?
Or does MSVC just hate exception specifications?
