Hi all,

please have a look at the code below. What are existing strategies to 
avoid the inconsistency? postscript does not know what to do with 
(x+y)/(x+y) in (x,y)=(0,0). Thank you


\psset{lightsrc=40 25 140,viewpoint=50 -45 30 rtp2xyz,Decran=60,unit=0.5}
% will compile
x add x y add div}
% won't compile
x add x y add div}
