Mine.

It makes no sense to loop block single nested loops.

> It makes no sense to loop block single nested loops.

Using -fgraphite-identity (not yet commited) or removing the ifdef at
graphite.c:4915 the Polyhedron also fails with this bug. So it seems not only
to be because of loop blocking.

All compiled with

Fixed on graphite branch.

We should open another bug once the -fgraphite-identity is in.
