--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> --- It doesn't fail on x86_64/i686 where I've tested it. Seems this is because r237426 has not been backported (and neither earlier r237319). Richard, do we want to backport those? Aren't those wrong-code fixes (besides also fixing this ICE)?
