--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> --- On the trunk I get similar corruption ICE with r242607, r242608 turns it into another ICE because of the broken avx5124fma patches, finally fixed with r242627. But 6 branch doesn't have the avx5124fma support, so r243404 should be enough.
