     Type:  Bugs              |     Status:  new
Milestone:  To Be Determined  |  Component:  container
  Version:  Boost 1.54.0      |   Severity:  Problem
 Keywords:                    |

 Reproducer:

 #include <iostream>
 #include <boost/container/flat_map.hpp>

 typedef boost::container::flat_multimap<int,int> IntMap;

 class MapTest {
 public:
     MapTest() {}
     MapTest(IntMap const &map) :
         _map(map) {
         _map.insert(map.begin(), map.end());
     }
     IntMap const& getMap() {return _map; }
 private:
     IntMap _map;
 };

 int main(int argc, char *argv[]) {

     using std::cout;
     using std::endl;

     IntMap iMap;
     for(int i = 0; i < 1000; i++) {
         iMap.emplace(i, i);
     }

     MapTest map(iMap);
     for(auto const &kvPair : map.getMap()) {
         cout << kvPair.first << " : " << kvPair.second << endl;
     }
     return 0;
 }
