 I followed the apple discussion thread above to:

 http://sourceware.org/gdb/wiki/BuildingOnDarwin

 following the advice there and in:

 http://lists.apple.com/archives/Darwin-dev/2009/Sep/msg00097.html

 I did the following to my local copy (on 10.6.2)

 sudo chgrp procmod gdb
 sudo chmod g+s gdb

 after building from the 7.1 cvs branch.

 after doing this I was able to successfully debug a fortran program built
 with mp gfortran 4.4 and 4.5.

 It only works for dwarf-2 not stabs+ (so -g alone should work but remember
 to keep the .o files).

 As a plus I can see fortran common block variables which doesn't work in
 the apple gdb.

 I do get a warning like this:

 warning: can't find section '__DATA.__common' in OSO file  XXX

 Also there are *lots* of warning like:
 warning:
 `/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_lang_gcc44/work/build/x86_64
 -apple-darwin10/libgcc/letf2_s.o': can't open to read symbols: No such
 file or directory.

 when you start the program but it seems to work anyway.
