> 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

"f951 -O1 -fdump-tree-graphite-all -fgraphite-identity name.f90"
