Comment (by lbartoletti):

 Here, the error lies in the orientation of the polygon. The geometry needs
 to be simple and in the counter-clockwise direction.

 I'm still wondering how to handle the "simple" cases where an
 ST_ForcePolygonCCW can resolve this issue. There are cases, like
 visibility (refer to my comment), that should return an error, but for
 this kind of scenario, should we also return an error or try to send a
 geometry that is most acceptable for (SF)CGAL?"
