#10531: Upgrade to boost 1.56.0 breaks compilation of boost::polygon code
------------------------+------------------------------
 Reporter:  fiesh@…     |       Type:  Bugs
   Status:  new         |  Milestone:  To Be Determined
Component:  None        |    Version:  Boost 1.56.0
 Severity:  Regression  |   Keywords:
------------------------+------------------------------
 The following code compiled until 1.55.0.  It stopped doing so from 1.56.0
 on.  I didn't mark the component as boost::polygon since it appears it
 wasn't changed and might be a problem related to something else.

 {{{
 #include <vector>
 #include <boost/polygon/polygon.hpp>
 int main()
 {
         typedef boost::polygon::polygon_data<int> Polygon;
         typedef boost::polygon::polygon_set_data<int> PolygonSet;
         PolygonSet ps;
         std::vector<Polygon> output;
         ps.get(output);
 }
 }}}

 My output (with gcc 4.8.3) is:
