--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Most likely r278983.  The ICE is on
3889                          else if (wi::ltu_p (min, wisiz))
where min->precision is 64 and wisiz->precision is 32.  That is invalid, ltu_p
etc. can be called only with the same precision wide_ints.
