 By the way, I was playing with different strategies combinations and I
 found out that when using only boost buffer strategies:

         double points_per_circle = 36;
         double distance = 130;
         bg::strategy::buffer::distance_symmetric<double>
 distance_strategy(distance);
 bg::strategy::buffer::end_flat end_strategy;
 bg::strategy::buffer::point_circle point_strat(points_per_circle);
 bg::strategy::buffer::side_straight sideStrat;
 bg::strategy::buffer::join_round joinStrat(points_per_circle);

 the buffer function can still fail (produce no output) when the distance
 is higher than 128 (e.g, 128, 130, 150, 300, 400). But this happens up to
 a certain value, where the buffer function starts producing a correct
 output (e.g., distances 900, 1000).
