Comment:

 I cannot confirm the fix for 1.57.0. The following code ...
 {{{
 _intPolygon polygon;
 boost::geometry::read_wkt("MULTIPOLYGON(((4287 2160,5984 2160,4287
 2160)))", polygon);
 boost::geometry::remove_spikes(polygon);
 }}}
 ... yields the following result:
 {{{
 MULTIPOLYGON(((4287 2160))))
 }}}
 As far as I can tell from our discussions, the correct result would be the
 empty multi-polygon. Here is the summary of my understanding of this
 issue:
