copied!<p>This code works (compiles & runs) for me:</p> <pre><code>#include <map> class MyObject { }; int main(void) { typedef std::map<int, MyObject*> MyMap; MyMap *myMap = new MyMap; MyObject *obj = new MyObject; myMap->insert(MyMap::value_type(0, obj)); delete obj; delete myMap; } </code></pre> <p>So the problem lies in the details (<code>// ...</code> or what <code>MyObject</code> can do) or elsewhere. You can probably fix things up a bit to help. Try to stack allocate things when you can. Do you actually need a pointer to a map? I suggest you don't:</p> <pre><code>#include <map> class MyObject { }; int main(void) { typedef std::map<int, MyObject*> MyMap; MyMap myMap; MyObject *obj = new MyObject; myMap.insert(MyMap::value_type(0, obj)); delete obj; } </code></pre> <p>And do you actually need to store pointers to object, or objects? </p> <pre><code>#include <map> class MyObject { }; int main(void) { typedef std::map<int, MyObject> MyMap; MyMap myMap; myMap.insert(MyMap::value_type(0, MyObject())); } </code></pre> <p>Much smaller, and almost impossible to get memory leaks. If you <em>do</em> need to store pointers, for polymorphic behavior, check out <a href="http://www.boost.org/doc/libs/1_39_0/libs/ptr_container/doc/headers.html" rel="noreferrer">boost::ptr_container library</a>, which has a <a href="http://www.boost.org/doc/libs/1_39_0/libs/ptr_container/doc/ptr_map_adapter.html" rel="noreferrer">map adapter that stores pointers</a>.</p>
