This (bad) code;
#declare AA = array[1] { x }
#declare AA = #declare AA[0] = y;
#declare AA = #declare AA[0] = z;
plane { y, 0 }
- results in this error message:
"The POV-Ray core rendering code caused an access violation exception."
- when I run it in POV-Ray for Windows v3.5
POV-Ray is not shut down after this error
message (and is able to render other scenes
correctly).
Can anyone else confirm this behaviour ?
My PC runs Win98 SE and has a 166MHz MMX
Pentium processor with 96MB of RAM.

I can confirm but it is what is called 'justice for wrong syntax' ;-)

I had hoped that this could be tested on
a MAC and a Linux machine too.
Further testing shows that this code:
#declare AA = array[1]
#declare AA = #declare AA = y;
#declare AA = #declare AA = z;
sphere { 0*y, 0 }
- leads to POV-Ray giving this error
message in the Messages window:
"Parse Error: Attempt to free NULL pointer
(File: ..\..\source\parse.cpp Line: 8222)."
I wonder if this is the same bug, or if
this one is somehow triggered by the zero
radius sphere. When I change the radius to
1 I get the same "Access violation" error
as with the first script I listed.

Confirmed on Debian Linux; kernel 2.4.18; Duron800MHz/256MB. POV crashes
with a segmentation fault. With a zero-radius sphere, gives the "attempt to
free a null pointer" error and segfaults.
