Hmm, I'm wondering why things get lost here..  It's been a while,  
maybe this is something inevitable, but I also remember when I was  
doing this a lot I would build Emacs.app with no optimization (remove  
-O2 in the compile script) and also use the debug version of the  
GNUstep libraries (I forget how I did this).  This definitely helps gdb.
