[Bug middle-end/38041] -O2 -fgraphite-identity causes ICE compiling channel.f90 Polyhedron 2005 benchmark

------- Comment #1 from howarth at nitro dot med dot uc dot edu  2008-11-07 02:45 -------
Compiling the rnflow.f90 benchmark with "-O2 -fgraphite-identity" produces the
same ICE...

rnflow.f90: In function Â‘rnflowÂ’:
rnflow.f90:4478: internal compiler error: in expand_scalar_variables_expr, at
graphite.c:3594
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.

Compiling  rnflow.f90 with "-O1 -fgraphite-identity" also ICEs with the same
error but
"-O0 -fgraphite-identity" doesn't ice the compiler.
