Hi, I found that the "electric-line-number" function in the fortran
mode works incorrectly when in overtype mode, in that it doesn't 
overtype.  It still inserts.  I don't really know emacs-lisp,  but
was able to put together a quick fix.  
Enclosed are the diffs. (My base was the fortran.el distributed in 
emacs version 18.55)
