Comment(by strk):

 So finally a valid GEOS bug. ST_IsSimple wasn't a good test but the one
 performed by the attached CheckNoding.sql script is, and clearly shows
 that UnaryUnion is failing to produce correct noding. There's a case of
 linear and puntual interior/interior intersections between returned lines.
