Yeah, sturm didn't help.

Is it just me, or is POV-Ray 3.5 a *lot* more sensitive to floating point
precision errors? I never had to pay attention in 3.1... I could use numbers
like .0000001 or so before things started messing up.

Incidentally, this problem doesn't occur with other simple primitives.
