     Type:  Bugs              |     Status:  new

------------------------------+---------------------------
 In the following example, the fourth point is actually a spike.
 ''remove_spikes'' does not remove it.


 {{{
 #include <iostream>
 #include <boost/geometry.hpp>
 #include <boost/geometry/geometries/geometries.hpp>

 namespace bg = boost::geometry;

 int main()
 {
         typedef bg::model::point<double, 2, bg::cs::cartesian> point_t;
         typedef bg::model::polygon<point_t> polygon_t;
         polygon_t poly{ { { 0.08039, 0.08076 },{ 0.836, 2.343 },
                 { 2.24, 1.874 },{ 1.452,-0.485 },{ 1.485, -0.3882 } } };
         bg::correct(poly);
         bg::remove_spikes(poly);

         return 0
 }
