The bug is bypassed by -fno-frontend-optimize, same as in the case of 66050 and
66386.

The ICE appeared between revisions r197010 (2013-03-23, OK) and r197238
(2013-03-29, ICE), likely r197216 (pr55806) or r197217 (pr45159).

--- Comment #5 from Thomas Koenig <tkoenig at gcc dot gnu.org> ---
As I wrote in the other PR, BLOCKs created by front-end optimization and FORALL
don't mix well.
The solution is not to attempt that particular optimization within a FORALL.
