--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
This is actually a regression, while in gcc 6 we for
-fsanitize=signed-integer-overflow ignored vector arithmetics (thus wouldn't
signal possible overflows), at least we computed the correct values, but now we
properly signal the overflow, but compute wrong values.
