Bug Description
I have discovered a strange behavior in pcb's design rule checker.
There is a 5mil by 5mil square that If I cover with a polygon, the DRC complains about insufficient overlap, and says that another trace far away doesn't have enough clearance. It doesn't matter how large I make the rectangle that covers the 5x5 square.
I initially had two large rectangles covering the area in an L shape, with sufficient overlap, but I was getting the same behavior, so I decided to try and cover as much of the layer as I could without causing the DRC error to occur. It turns
I've attached the PCB file.
The 5x5 square in question is @ 1995, 2530 on the layer named V5
Unfortunately the pcb isn't very simple, but at least the change in the pcb is.

When I run a DRC on the supplied board, I don't see any errors raised.
However, when I move the mouse around, I get segmentation faults. This needs to be addressed immediately.
