I am able to start emacs (as a carbon app) with this change, but the  
resulting Emacs is very slow, taking over a second to respond to key  
presses, but not eating gobs of CPU.   I started emacs -Q under gdb  
to see if I could figure out where it was spending all its time, and  
got a crash.  This seems to be repeatable, always in the same place,  
with param_index = 56.  I tested without any .emacs file, also.
