 XEmacs 20.4 doesn't crash because a more complete update of the
 frame is forced (SET_FRAME_CLEAR;) at the beginning of Frecenter
 (which Hrvoje removed for 21.0). This isn't done in the
 (Lisp-)recenter of 21.0. 
If I understand you correctly, the "quick fix" would be to add
SET_FRAME_CLEAR to Fredisplay_frame, wouldn't it?

 The right fix should in my opinion be done in widen_buffer (and
 maybe plus some change in the redisplay code). Here we have to
 either adjust the start-marker or make redisplay do that later on. 
If you could send out a patch, it would be great.  Thanks for the
analysis.
