Ok, noted. (Although a shorter example would have been nicer...)

Curiously it doesn't crash in the unix version...

Because there is change 1526...

Then the name of 1526 fix should be fixed to "Final fix for radiosity
recursion problems" in next RC then ;-)

After walking around rotated monitor I have good news for you Chris :-).
On my tests crash disappear when sequence of:
> #macro IC_Matrix (Fn, Mtrx)
> #macro IC_RotateR (Fn, Vect)
> #macro IC_Rotate (Fn, Vect)
is replaced with short
#macro IC_Rotate (Fn, Vect)
#local f_T=function{transform{rotate -Vect}};
function{Fn(f_T(x,y,z).x,f_T(x,y,z).y,f_T(x,y,z).z)}
#end
It not changes that your macros shouldn't crash however you can make stable
version. I think in correct form it shuld rather
transform{rotate Vect inverse}

No, because it did not fix the problem, it simply restored the old behavior.
The changes which caused the problems were made because some other part was
using much more stack space then really necessary. The best solution was to
move some arrays that were allocated on the stack into arrays allocated in the
heap and to add a pool that prevents frequent (and thus time-consuming)
allocating/freeing. The side effect of this is that more layers are now
supported in texture tests (which is noted in the same change). So fixing one
bug (http://news.povray.org/povray.beta-test/21445/) adds a feature as well
:-)

I found the problem. There currently is no workaround other than using less
complex functions.
In fact the problem is fairly serious but random in nature because it is
related to a changed pointer returned by a realloc() not getting used
everywhere...

Does this mean it will be fixed in next beta?
