TL;DR: The mingw-w64 function is linked statically and subject to issues about order of destruction. Recently mingw-w64 has got its own `__cxa_thread_atexit()` so libstdc++ no longer exposes it. This patch for libstdc++ fixes calling conventions for destructors on i686 so they match mingw-w64 ones.
Any more comments? I'd like to push this soon if there are no more issues open.
