This doesn't crash for me. I don't know why. Try the latest CVS after I
have commited my patch.
It didn't crash for me either with -vanilla. After a bit of
experimenting I discovered that the problem only occurs if
scroll-step is non-zero. If you run xemacs -vanilla and (setq
scroll-step 15) then ediff-files will crash in the call to vmotion
from redisplay_window around line 6148 in redisplay.c. I haven't
tried to figure out exactly why, I hope it will be obvious to you now
that you know what's failing.
