--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
Confirmed. Another case hanging in SCEV stuff. This time in cunrolli.
It might be caused by my removal of some complexity backoff ...
Martin, can you confirm that?
Eventually caching isn't working too good either so we do very many times
the same thing (infer_loop_bounds_from_undefined). Seemed to work fine
in GCC 7 for whatever reason (not unrolling so much I guess).
I will have a look.
