[Bug fortran/17878] New: Internal compiler error

["sfilippone at uniroma2 dot it" <gcc-bugzilla at gcc dot gnu dot org>]

This is a strange one: the compiler segfaults on one of the modules in the file,
but only if the last module is present; if the last module is commented out, it
works. In fact, this test case (sorry I couldn't make it shorter while
preserving the error) is derived from a multiple-file compilation. I am
attaching the test case separately, here is the output
