Comment (by strk):

 This seems interesting. Of the 3 calls to ::buildMaximalEdgeRings, each
 for each polygon
 in input, only one returns a "maxEdgeRing":

 0x7fff2ad7da30] PolygonBuilder::buildMaximalEdgeRings got 2 dirEdges
 0x7fff2ad7da30] PolygonBuilder::buildMaximalEdgeRings returning 1
 maxEdgeRings

 0x7fff2ad7da30] PolygonBuilder::buildMaximalEdgeRings got 2 dirEdges
 0x7fff2ad7da30] PolygonBuilder::buildMaximalEdgeRings returning 0
 maxEdgeRings

 0x7fff2ad7da30] PolygonBuilder::buildMaximalEdgeRings got 2 dirEdges
 0x7fff2ad7da30] PolygonBuilder::buildMaximalEdgeRings returning 0
 maxEdgeRings
