Crashes for me too (after 99% of render). 3.5 beta9.icl.win32  p3 733 W2K

Here's an oddity. The modified code below outputs this to #debug:

-1.#J
-1.#J
-1.#J
-1.#J
-1.#J
-1.#J
-1.#J
-1.#J
-1.#J

Huh?

Here's the modified code

#declare n=1;
#declare i=-1;
#while(i<=n)
  #declare j=-1;
  #while(j<=n)
    #declare tt=((-0.1)^(0.1));
    #debug concat(str(tt,2,2),"\n")
    //sphere{<0,0,0> 1 }
    #declare j=j+1;
  #end
  #declare i=i+1;
#end

(no crash with sphere commented out).

Thinking about it, aren't you trying to find the root of a negative number here?
