--- Comment #1 from Oleg Endo <olegendo at gcc dot gnu.org> ---
Ouch, yes, constraints missing. Thanks for the reduced test case.
The patch below fixes it. I'd apply it to trunk and 4.9 without further
testing, as it's obvious, I think. Kaz, if you'd like to run it through your
test setup, I'll wait.

BTW, funny div0s use case.
