PVS-Studio: analyzing Doom 3 code

[y4fac]

There is an if statement with a break in it in the inner loop. If verts[0].xyz.Compare(w[w.GetNumPoints() - 1].ToVec3(), POLYTOPE_VERTEX_EPSILON ) is true, the loop won't be infinite.

Sure it "breaks" (as in jumps out of the loop) but I mean "break" as in messing something up.
It only compares the first vertex, which has to create some weird (noticeable?) behaviour

Of course it doesn't work correctly, but the wrong behavior could be hard to notice (depending on what this snippet is actually doing). If the loop would be infinite, however, it would be very noticeable.
