--- Comment #9 from Bill Schmidt <wschmidt at gcc dot gnu.org> ---
OK, I've now confirmed this is the problem. I have a rough patch for trunk,
and backporting it to GCC 5 r236439 verifies that this fixes it. Still
verifying bootstrap/regression on trunk, and need to do some cleanup before
submitting.
