Re: Big desktop undo buffer crashes Emacs

>From my previous reply:

   I said that it might solve "part" of your problem.  The question is
   whether the 3M of undo is legitimate.  Take a look at what is in that
   buffer.  Does the huge size of the buffer seem legitimate, because
   there really is that much info to save?  I guess that you know that
   you can produce the buffer using `M-x desktop-save'.

Well, the size of the undo info is not necessarily related to the size
of the buffer.  In my setup, after `M-x desktop-save', I get a
*desktop* buffer of size 2943, but my buffer-undo-list (_without_ my
patch applied) is very small:

(nil
 (1 . 2944)
 (t 0 . 0))

I guess that if you created the *desktop* buffer and did 
`C-h v buffer-undo-list' in it, you would get a really huge *Help*
buffer, assuming it would not make your Emacs crash.

Sincerely,

Luc.
