What I am doing is creating a Military Tank using CSG. I detected that a part of
the tank was hollow, or "semi-hollow". The same thing that happens when you
extract an object from itself:
difference
{
   box{A,B}
   box{A,B}
}

But I am aware of that problem and I always avoid it. So I made a detailed
inspection of the code. After hours of checking the code I finally found the
bug.

The code I posted here is just a minimal example of how to reproduce the bug.

Of course I can fix the thing with some "tricks", but that is not the point, I
think is better if a bug is fixed rather than avoiding it using tricks.

I am not asking for a way to avoid the bug, what I want is to inform the
existence of this bug.
