Is this bug still around (r156830)? I have a 64 bit linux machine and it seems
to be fine.

different testcase, reduced
Fails at all -O1, -O2 and -O3 levels. I am not sure if it is the same problem,
but it fails at the same place, so I am attaching it here.

I believe this commit introduced the bug:
Remove COMPONENT_REF limitation in SCoP detection.
2010-01-08 Sebastian Pop <sebastian.pop@amd.com>
* graphite-scop-detection.c (exclude_component_ref): Removed.
(is_simple_operand): Removed.
(stmt_simple_for_scop_p): Remove use of is_simple_operand.
git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/branches/graphite@155738
We allow SCoPs that we cannot handle in the backend.
