looks like you discovered an independent bug, in my case the 'cat t.f90' wasn't
part of the program (but it is the command line that wraps) and in my case
there is no error message.

Jerry is our expert on this side of things.  Although he has said that he is in
temporary hiding from gfortran, I have CC'd him:)

The patch is straight forward.  Need to check for end of file after
advance_line in scanner.c in a couple of places.  I just need to finish testing
and package the  submit.  Maybe tonight.

No need to go to 4.1.  This is an ICE on invalid.
