Comment (by OoS):

 Replying to [comment:2 nomeata]:
 > Could you try to minimize the example? I.e. remove code or replace it by
 constants and see if the problem still occurs, and then repeat until you
 cannot simplify it further.

 I've tried that before, but if i remove where clauses from "buildFrustum"
 the error doesn't occur, so i must show all the code. I try to make a
 simpler test case.
