The good news: I haven't seen a repeat of that old crash so far. 
Unfortunately, I'm finding that emacs is unstable:  The emacs window 
(running under X) simply disappears after 12-24 hours.  This may not 
have anything to do with the most recent changes.  I haven't yet tested 
any earlier snapshots.

Testing this is a very slow process, since I don't know how to produce 
the problem; I just have to wait and see if emacs will die.

I tried to get some information by running emacs under gdb the most 
recent time I started it, but all I got was this:

(gdb) c
Continuing.
[Inferior 1 (process 8196) exited with code 05400]
(gdb) bt
No stack

Does that exit code mean anything to you?  I couldn't find anything by 
googling.

Ken
