typedef std::map<int, MyObject*> MyMap; MyMap* myMap = new MyMap; // ... myMap->insert( MyMap::value_type( 0, objectOfType_MyObject ) ); Why does my code crash with a stack trace going down to std::less<int>::operator() ? I understand that if I use a custom key class that I must provide a comparator, but this is an int. I'v...
