compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.

I'll see if can get more info. gfortran should really have an option to
generate a single 'preprocessed' file, without module dependencies. It would
simplify test case generation.
