I have just committed Tom's work (rev 5741), as it fixes a bug marked as critical [1] and hopefully resolves all other problems related to boost::polygon library. If you face any problems filling polygons, there is an option to revert to the legacy zone filling algorithm (Preferences -> General -> Advanced/Developer -> Use legacy filling algorithm) and please report such cases. Thanks Tom! Regards, Orson 1. https://bugs.launchpad.net/kicad/+bug/1459720
