[Boost-users] [ICL] Map & insertion

Hello, I declared an interval_map : interval_map myMap; and two intervals : discrete_interval( 0,10) interval_1; discrete_interval(10,17) interval_2; Later, I do : myMap.insert(std::make_pair(interval_1, SOME_ENUM_VALUE_1); myMap.insert(std::make_pair(interval_2, SOME_ENUM_VALUE_2); The second insertion hasn't any effect. I tought that by default, the upper bound was excluded. If so, there isn't any overlapping. So why does that failt ? By debugging, I cna see that somewhere in the ICL code, the second value is tested as "absorbable"... Thanks for help.
