[Bug fortran/30793] Segfault on calling a function returning a pointer

[sfilippone at uniroma2 dot it]

------- Comment #4 from sfilippone at uniroma2 dot it  2007-02-14 20:35 -------
I fail to see how xlf's output can be correct on the first error; fld%msh is a
POINTER component. ANd get_scalar_field_msh is set. So  there must be something
else going on. Intel fortran 9.1 digests it without a glitch.
