--- Comment #22 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
BTW, wonder if it wouldn't be desirable to revert the PR114361 patch until this
is sorted out, or at least limit the effects of that patch to flag_isoc23 and
using multiple types with the same tag and same content.
Like guard
TYPE_CANONICAL (x) = TYPE_CANONICAL (t);
with if (flag_isoc23 && TYPE_CANONICAL (t) != t)
Because otherwise the trunk is just completely broken for all of LTO with C of
any version.
