The Polyhedron 2005 benchmark aermod.f90 ICEs the gfortran compiler when
compiled with...
gfortran -O2 -fgraphite-identity -floop-strip-mine aermod.f90 -o aermod
producing the error...
aermod.f90: In function chk_endyr:
aermod.f90:5620:0: internal compiler error: Floating point exception
This error doesn't occur with...
gfortran -O2 -fgraphite-identity aermod.f90 -o aermod
..or...
gfortran -O2 -fgraphite-identity -floop-interchange aermod.f90 -o aermod
Using built-in specs.
