I was unable to reproduce this. I rendered the first one(320*240, no AA) 
then rendered the second, and repeated this, but nothing goes wrong.
Are you using just the sources I uploaded, or are you adding them to 
your version? If you are adding them to your version, make sure add the 
code which copies and destroys proxObj.

Hmn, I don't think this should be a problem, but to destroy the object, 
I used this:
  if(Tpat->proxObject != NULL)
  {
      Destroy_Object((OBJECT *)Tpat->proxObject);
      POV_FREE ((OBJECT *)Tpat->proxObject);
  }
Is the call to POV_FREE necessary? I don't think it is.
I had copied it from Destroy_CSG, and interpreted it as destroying the 
pieces of the object, but not freeing the actual object. Now that I look 
at it more closely, this seems likely to be the problem. Try deleting 
the line
      POV_FREE ((OBJECT *)Tpat->proxObject);
and see if that fixes it.
