I seem to have encountered a GNU Emacs 18.55 bug on our HP 9000/840;
the debugger backtrace and dribble file follow.  They were generated
on a emacs process started up with the "-q" option.

The problem is reproducible:  I load Edward Reingold's calendar
package (I can mail a copy if it's needed) and enter/exit it 4 times.
If I enter it a 5th time, emacs garbage-collects, and signals the
following error if I attempt to exit.

 -------- Backtrace --------
Signalling: (wrong-type-argument window-configuration-p #<EMACS BUG: ILLEGAL DATATYPE (#o37777777765) Save your buffers immediately and please report this bug>)
  set-window-configuration(#<EMACS BUG: ILLEGAL DATATYPE (#o37777777765) Save your buffers immediately and please report this bug>)
  (progn ...)
  (if ...)
  (let ...)
  exit-calendar()
* call-interactively(exit-calendar)
 -------- Dribble File --------
xset var
 ---------------------------

The problem may be specific to this machine hardware; it doesn't
happen on a VAX.  If you need access to our machine for debugging,
or need more information, I'll be glad to help.
