emacs hang

[Robert Mecklenburg]

I'm running the lastest cvs sources (updated and compiled 2004-04-30
8:00MDT).  I had debug-on-error set and a two frame stack trace for
some simple error and emacs hung.  I would not respond to C-g
although the text cursor was still blinking occassionally. 

I was running emacs under gdb, so I sent it a C-c and got this stack
trace:
