Getting lot of warnings for simple code which is using boost::Intersection

[sumanth.kaliki@…]

The simple code below is generating a lot of warnings in boost 1_61_0 version.

#include <boost/geometry/core/cs.hpp>
#include <boost/geometry/geometries/register/point.hpp>
#include <boost/geometry/geometries/polygon.hpp>
#include <boost/geometry/geometries/register/ring.hpp>
#include <boost/geometry.hpp>

struct Vertex2D
{
    double X;
    double Y;
};

BOOST_GEOMETRY_REGISTER_POINT_2D(Vertex2D, double, cs::cartesian, X, Y);
typedef std::vector<Vertex2D> Ring;
BOOST_GEOMETRY_REGISTER_RING(Ring);
typedef boost::geometry::model::polygon<Vertex2D> Polygon;

int main()
{
    Polygon p1;
    Polygon p2;

    std::vector<Polygon> intersections;
    boost::geometry::intersection(p1, p2, intersections);

    return 0;
}
