Comment (by strk):

 The code counts the number of vertices that fall within the clipping box.
 In your case, there are NO vertices in the box, right ?
 In that case, the code checks if the polygon contains one corner of the
 box and if it does, it returns a fully filled box, otherwise it returns
 nothing.

 Well, in your cases the box contains NO vertices but it still cuts the
 polygon, so it's neither a full solid nor a missing. If this analysis is
 correct, the code is bogus.

 It will be a fun exercise at finding the smallest input that can reproduce
 the problem.
