Buffer() Seg Faults with Ring as Input

[xmrflipflop]

On boost version 1.58.0 and C++14, boost geometry buffer with strategies fails when the input geometry given is a ring. Changing the type to a polygon behaves as expected.

I don't have newer boost versions available for testing unfortunately.

Test code below.

        std::cout << "Using Boost "
                  << BOOST_VERSION / 100000     << "."  // major version
                  << BOOST_VERSION / 100 % 1000 << "."  // minor version
                  << BOOST_VERSION % 100                // patch level
                  << std::endl;

        // Set up boost geometry types
        namespace bg = boost::geometry;
        using point_type = bg::model::point<float, 2, bg::cs::cartesian>;
        using polygon_type = bg::model::polygon<point_type>;
        using ring_type = bg::model::ring<point_type>;

        // Declare strategies
        constexpr float buffer_distance = 0.5F;
        const int points_per_circle = 36;
        bg::strategy::buffer::distance_symmetric<float> distance_strategy(buffer_distance);
        bg::strategy::buffer::join_round join_strategy(points_per_circle);
        bg::strategy::buffer::end_round end_strategy(points_per_circle);
        bg::strategy::buffer::point_circle circle_strategy(points_per_circle);
        bg::strategy::buffer::side_straight side_strategy;

        bg::model::multi_polygon<polygon_type> bufferedPolygon;
        ring_type originalPolygon;
//        polygon_type originalPolygon;

        bg::append(originalPolygon, point_type { 14.4980001F, 10.5F });
        bg::append(originalPolygon, point_type { 14.4980001F, 12.420001F });
        bg::append(originalPolygon, point_type { 15.9980001F, 12.420001F });
        bg::append(originalPolygon, point_type { 15.9980001F, 10.5F });
        bg::append(originalPolygon, point_type { 14.4980001F, 10.5F });

        bg::correct(originalPolygon);

        bg::buffer(originalPolygon, bufferedPolygon, distance_strategy, side_strategy,
            join_strategy, end_strategy, circle_strategy);

Can confirm same behaviour with C++11 and current geometry-develop branch.

I can reproduce this. Will look at it next Wednesday.

Sorry, it was not next Wednesday, but (hopefully) still in time to make it for 1.64.
