Another data point:  no appearance of the bug without ruler-mode:

      emacs -q --no-site-file
      C-h C-n
      M-x ruler-mode

      <down>...                                   ; all works as expected

      M-x set-variable scroll-conservatively 1000 ; any non-zero value

      <down>...                                   ; bug happens when cursor
                                                  ; is in the last line and
                                                  ; you scroll down

   Thank you.  Yes, this recreates the redisplay bug.  

However, these actions do not recreate the bug if you do not start
ruler-mode, at least, not in a slightly newer CVS snapshot (this
morning's, not yesterday's).  

I did everything else the same as shown above, but did not start
ruler-mode; no bug visible.  But when I did the same as described
above, turning on ruler-mode, the bug appeared.

   Using today's CVS snapshot, Fri, 2002 Jul 19  11:51 UTC
   GNU Emacs (i686-pc-linux-gnu, X toolkit),
   which has 
   the patch from address@hidden (Kim F. Storm) to xdisp.c 
   merged in,

   Emacs started with:

       emacs -q --no-site-file --eval '(blink-cursor-mode 0)'
