--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
This first started to ICE in r254867, with:
internal compiler error: in transform_to_exit_first_loop, at
tree-parloops.c:2004
In r258713 it changed into a checking ICE:
error: mismatching comparison operand types
signed int
unsigned int
if (ivtmp_32 < 3)
during GIMPLE pass: parloops
pr86097.c:4:1: internal compiler error: verify_gimple failed
