When compiling the aermod.f90 from the Polyhedron 2005 benchmarks with gfortran using either...
gfortran -ffast-math -floop-block -O2 -fgraphite aermod.f90 or gfortran -ffast-math -O2 -floop-strip-mine -fgraphite aermod.f90 results in the compiler error... aermod.f90: In function vrtcbl: aermod.f90:14521: internal compiler error: in instantiate_scev_1, at tree-scalar-evolution.c:2220 Please submit a full bug report, with preprocessed source if appropriate. See <http://gcc.gnu.org/bugs.html> for instructions.
