It appears to have going on for a while now, my last successful bootstrap of
trunk was with the 20150419 snapshot. Starting a bisection now.

--- Comment #7 from Eric Botcazou <ebotcazou at gcc dot gnu.org> ---
It's a known fragility of the SPARC back-end in 32-bit mode, which really wants
to forbid DImode values in odd-numbered registers. The problem is that the
calling conventions for 'long long' disagree, so DImode destinations can be
odd-numbered registers in the end...
