Small test exhibiting the problem.

I am one of the fluidity development team. 

This is a very cut down source which exhibits the problem. It produces the
following compiler output:

dham@hex foo > gfortran-4.6  -c foo.f90 
foo.f90:103:0: internal compiler error: in gfc_is_constant_expr, at
fortran/expr.c:906
Please submit a full bug report,
with preprocessed source if appropriate.

>From the experience of cutting down the source to this test, I think it's
something to do with the generic interface "size".
