I believe that gdb is the best available option, at present, despite the 
problems.  We would of course very much welcome patches to improve its 
support for Fortran programs!

Also, I suspect (but this is just a guess) that a lot of the problems 
such as the one in that bug report are at least in part on gfortran's 
side of things, rather than gdb's side.  It's not immediately clear what 
version of gfortran you're using, but if you're filing the bug against 
Debian it's probably an older 4.1 version, and lots of bugs have been 
fixed since then.  I don't recall if this is one of them, but it may be 
worth trying a current 4.3 snapshot to see if the problem persists.
