--- Comment #7 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
The infinite loop is there since
r8-5095-gd49e06ce40a76c3f6e96bf2eccb59db19d4d2b1d
and while r10-3676-g806bdf4e40d31cf55744c876eb9f17654de36b99 made it go away
again, since r10-4704-gf0af4848ac40d2342743c9b16416310d61db85b5 the outer
(rather than inner) loop is infinite.
