I don't think so.  Another way to trigger the bug: enable
global-font-lock-mode, load some C file, resize Emacs so that the last
line is only partially visible, ie. the frame size is not a multiple of
the font size.  Now type M-> to go to point-max and scroll up one line at
a time (M-1 M-v).  As soon as the cursor hits the last frame line the
display is garbled.  This happens only when point is at point-max.

Andreas.
