Of course.  And another "of course" is gdb.  Don't know why I wasn't 
thinking....

I seem to be able to trigger is by doing outline operations.  When it 
happened I used AUCTeX and LaTeX source. The backtrace (included below) 
seems to indicate internal problem?  I'll start running tests using 
only distrib stuff and with emacs -q and try to get a better bug report 
together, but I enclose the trace here anyway in case anyone can say 
anything based on it?

I have now triggered it using both Emacs/Carbon and Emacs/X11 (both 
running under Mac OS X).
