Emacs carbon crash, and beginner question...

[Martin Fredriksson]

I just experienced a couple of crashes in Emacs carbon (current build). 
 Just died, no message, nothing.  Yes, yes, I know this is a stupid 
thing to say to you all; I'm just setting the stage for following even 
lamer question:

Is there a quick way to read up on how to get Emacs (particularly 
Carbon) to log more, run it in debug mode, or otherwise helpful things 
to get some more info about intermittent crash problems?  Just knowing 
whether it was Emacs itself which decided to quit silently or if some 
OS function is the source of problem would be very useful.  I guess 
what I'm asking for is pointer to docs to read, tips, etc, with the 
goal of getting a quick start into more serious Emacs debugging.
