--- Comment #7 from Mikael Pettersson <mikpelinux at gmail dot com> ---
The recent backport of the PR59715 fix to the 4.7 branch caused the PR60382
regression to also appear there:

> /tmp/objdir/gcc/xgcc -B/tmp/objdir/gcc -O3 -c pr60382.c
pr60382.c: In function 'foo':
pr60382.c:4:1: internal compiler error: in vect_create_epilog_for_reduction, at
tree-vect-loop.c:4180

[4.7-20140510 on x86_64-linux]

Backporting the PR60382 fix from 4.8 to 4.7 fixes the ICE.
