--- Comment #4 from Sam James <sjames at gcc dot gnu.org> ---
It bisects to r15-8901-g7bec4570301c43 which I find very surprising. Double
checked with a build of r15-8900-g525d4a10302113 (which works) and
r15-8901-g7bec4570301c43 (which doesn't).

I'll get the bits richi asks for but may not be until the weekend.
