--- Comment #16 from Jonathan Wakely <redi at gcc dot gnu.org> --- Thanks. As per https://gcc.gnu.org/lists.html patches for libstdc++ need to be CC'd to the libstdc++ list, but I'll find it in the gcc-patches archive and review it ASAP. I'm still concerned that this just moves the problem, so that different cases fail instead. But maybe it's an improvement for the most common case, and it's better to fail in the rare situations.
