--- Comment #3 from Yuri Rumyantsev <ysrumyan at gmail dot com> ---
It turned out that after r235653 (with minor int->bool type change) 176.gcc
started RF. If we turn off vrp phase benchmark passes. The problem fail is
sched.c. Note that avx2 is essential for reproducing. Try to understand what
the issue is.
