Here are some more details from my experiments.

If you compile sedov (FLASH 2.2 or 2.3) with some checking/debugging
options: "-C -d -g", you'll find that:
 - one file does not compile with -C (perfmon.F90) due to "internal
compiler error"
 - in mark_grid_refinement.F90 there is a mysterious problem with
array size/shape/rank/something, which doesn't appear when compiling
with pgf90.

I tried to run and compile on several machines with Intel and AMD
processors, slightly different glibc, and the result was the same. It's
a bit sad because (AFAIK) ifc is the only F90 compiler available for
free.
