bug#555: crash in redisplay_window> temp_set_point_both

[David Reitter]

I just experienced a rather random crash during redisplay.
It's hard to pin down.  This is a patched 22, most notably with the  
DTWW stuff backported.
temp_set_point_both is not affected.

How does one tell what code line corresponds to temp_set_point_both +  
85?
