For example, inserting {2, 3} into {1, 4} should result in {1, 2, 3, 4}, but we get {1, 4}. [[BR]] While inserting {2, 4} into {1, 3} give us {1, 3, 4}, 2 is lost somewhere. [[BR]] It seems that you can only insert elements ordered after the range." Bugs closed Boost 1.52.0 container Boost 1.51.0 Problem fixed tongari95@… phprus@…
