This is a regression issue found in 1.41.1-beta and 1.41.1-rc, caused by the clipper library creating self-intersecting contours, and successively the EdgeGrid routine incorrectly identifying the inside / outside property of the polygons.

The fix consists of regularizing the self-intersecting contours.
Fixed with eb59568

It will be part of the 1.41.1 final release. Closing.
