[Bug fortran/30902] New: gfortran produces wrong result with code using generic interface block

["deji_aking at yahoo dot ca" <gcc-bugzilla at gcc dot gnu dot org>]

The attached test code using a generic interface block produces wrong output
when compiled with gfortran, and works fine with pgf90. Tested with gcc trunk
and gcc-4.2.0
