This simplified code causes a stable crash (POV 3.5 b9 PIII-1000 512 Mb
Win2000):
It's OK if one of #while blocks or sphere is removed.
//-------8<----------
#declare n=1;
#declare i=-1;
#while(i<=n)
#declare j=-1;
#while(j<=n)
#declare tt=((-0.1)^(0.1));
sphere{<0,0,tt> 1 }
#declare j=j+1;
#end
#declare i=i+1;
#end
//-------8<----------

I can't confirm. Works properly on my machine.

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?

I think it's trying to say "-1.#IND", indicating an invalid number.
Because you only allowed it to display 2 places of decimals, it has
rounded up the "I" to "J". In the same way, if you allow 1 or 3 places
of decimals it will round the "#" up to "$" or the "N" up to "O"
respectively.

Wow! Thanks Sherlock. YNYHBUCTL when the idea of rounding ind to j seems
aesthetically pleasing....
Presumably that's the -0.1^0.1 ?

Yeah... probably. Negative numbers to fractional powers are undefined, I
believe.

Of course, the result of this operation is undefined.
The strange part is that the crash takes place only inside at least two
#while blocks.
Maybe it's about stack memory releases when handling an error event?
