--- Comment #41 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
That is true, but we've got only a single bugreport about this since the 5.2
release (21 months), so it doesn't trigger that often.  For static data members
the ABI is self-consistent, for some template types in templates it is indeed
not if the instantiation is different before the instantiation of those
templates.  By changing the ABI now in 5/6 I'm afraid we'd break far more code
than is already broken.
