Back in April, I told Harald I would get around to committing
the attached patch. Well, "around" has arrived. The patch
has been tested on i586-*-freebsd and x86_64-*-freebsd.
The patch converts an assert into a gfc_fatal_error(), which
gives a user some information about the failure. There is
no testcase as one need to go out of one's way to corrupt
the components in a derived typed in a *.mod file.

* module.c (read_module): Convert assert to fatal error to give
user a sensible error message.
