Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.

This was tested on the graphite branch. The reduced testcase from polyhedron
benchmark is attached.

Polyhedron also fails with this bug in, if you use -fgraphite-identity in the
graphite branch.

It seems we do not have implemented all cases in expand_scalar_variables_expr()

Backtrace for "f951 -O2 -fgraphite-identity".
