[Bug fortran/37379] New: ICE compiling aermod.f90 with -ffast-math -floop-block -O2 -fgraphite

[howarth at nitro dot med dot uc dot edu]

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.

This error doesn't occur when the -ffast-math flag is not used.
