--- Comment #29 from Kazumoto Kojima <kkojima at gcc dot gnu.org> --- (In reply to Oleg Endo from comment #28) > Can anybody comment on the state of this problem here? Were the two commits > in comment #2 and comment #3 merged into mainline at some point? AFAIK, those patches weren't merged. I guess that other changes for apply/return buitins fix the failure, though I'm not sure if the original issue went away completely.
