Sometimes the scan finds nothing that qualifies for addition to the array and pos is zero after the loops. The code forces pos to 1 and the array is then processed as if it had one valid element in it, producing some amusing but not very useful results. I don't see the rationale for this. If pos is zero coming out of the loops, the only appropriate thing to do is set t->angle to zero. The attached patch does that. It's worked properly in several tests so far.
