Buffer fails for large distances

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).

Needs intersecting piece-sides too (like for flat-ends for linestrings)
