This problem happened in the graphite branch where after the graphite
pass we scheduled a pass of loop invariant motion (LIM). LIM does
expect to see the loop closed SSA form, but that property is not
maintained by the code generator of graphite. The testcase is
extracted from the polyhedron benchmark aermod.f90 and it failed on
graphite branch when compiled with -O3 that implies -floop-block and
-fgraphite-identity.
