again, hi all.... After writing an example to demonstrate the problem, as per Peter's request, I could not repro it, until I added this extra line glutMainLoop(); before the return 0; of main.cpp. As for those how might not know that glutMainLoop does.... Enters the GLUT event processing loop, never to return. One would use the GLUT library when writing OpenGL applications. If I comment out this line, then I can account for every single class destructor call, i.e. no leaks. When it is NOT commented, then most of the class destructor calls do not get called, or printed (this I will verify) and therefore my guess is that there are leaks. Anyway, since I have done the work to write the test case, I might as well post it. This code does NOT contain the glutMainLoop() I mentionned. I could do so if required, but Id need to also send you a makefile. When I figure out what is going on, I will let you know... If anyone has any ideas, please feel free to share! Thanks, Eric Test code..... /*****************************************************************************/ // main.cpp /*****************************************************************************/ #include <iostream> #include <string> #include #include #include #include #include using namespace std; using namespace boost; /*****************************************************************************/ // class CObject { protected: CObject(){}; protected: virtual ~CObject(){cout << "CObject cleanup" << endl;}; public: virtual void SetObjectName(const string& strName) = 0; virtual const std::string GetObjectName() = 0; }; // class C1 : public CObject { public: C1(){}; protected: virtual ~C1(){cout << "C1 cleanup" << endl;}; public: // Copy constructor C1(const C1& object) : CObject(object){}; }; class C2 : public C1 { public: C2(); C2(const string& strName) : m_strName(strName) {}; ~C2(){cout << "C2 cleanup" << endl;}; public: // Copy constructor C2(const C2& object) : C1(object), m_strName(object.m_strName) {}; // Data private: string m_strName; public: inline void SetObjectName(const string& strName) {m_strName = strName;}; inline const std::string GetObjectName() {return m_strName;}; }; // struct graph_node_t { enum { num = 1000 }; typedef boost::vertex_property_tag kind; }; struct Print { template<class T> Print& operator() (const T& t) { std::cout << t << endl; return (*this); } }; // class CTester { public: CTester() {}; ~CTester() {cout << "CTester cleanup" << endl;}; // Graph stuff private: typedef boost::property node_name_t; typedef boost::property node_property_t; typedef boost::adjacency_list graph_t; typedef graph_traits::vertex_descriptor vertexdescriptor_t; graph_t m_Graph; // private: inline boost::shared_ptr<CObject> getNodeProperty(const vertexdescriptor_t& vertex) { boost::property_map::type node_prop_map; node_prop_map = boost::get(graph_node_t(), m_Graph); return node_prop_map[vertex]; } boost::shared_ptr<CObject> getNodebyName(const std::string& strName) { boost::shared_ptr<CObject> node_prop; boost::graph_traits::vertex_iterator vi, vi_end; boost::tie(vi, vi_end) = boost::vertices(m_Graph); for(; vi != vi_end; ++vi) { node_prop = getNodeProperty(*vi); if(node_prop != 0) { if(node_prop->GetObjectName() == strName) break; } } return node_prop; } // public: template <typename T> void addObject(const T& object) { // Create a vertex boost::shared_ptr<T> spObject(new T(object)); // Add the vertex + its name to the graph boost::add_vertex(node_property_t(spObject, node_name_t(spObject->GetObjectName())), m_Graph); } template <typename T> boost::shared_ptr<T> getobject(const std::string& strName) { boost::shared_ptr<CObject> abc = getNodebyName(strName); shared_ptr<T> def = boost::dynamic_pointer_cast<T>(abc); return def; } void PrintObjects() { graph_property_iter_range::type test = get_property_iter_range(m_Graph, vertex_name_t()); cout << "Printing all vertices:" << endl; std::for_each(test.first, test.second, Print()); } }; /*****************************************************************************/ int main(int argc, char **argv) { CTester tester_class; tester_class.addObject(C2("class one")); tester_class.addObject(C2("class two")); boost::shared_ptr<C2> abc = tester_class.getobject<C2>("class one"); cout << abc->GetObjectName() << endl; return 0; } /*****************************************************************************/ Peter Dimov wrote:

hi all, quick question concerning shared_ptr... not sure if things get deleted (destroyed) properly and its freaking me out. I hope this is not too long [...]

Please post a complete example that demonstrates the problem. _______________________________________________ Boost-users mailing list Boost-users@lists.boost.org http://lists.boost.org/mailman/listinfo.cgi/boost-users

I have tried everything except the most obvious. No it does not!!!!!! arghhhh Thanks... I will find a way around this, Eric Rene Rivera wrote:

Only the obvious one that the glutMainLoop does a direct to system exit. Have you verified that it reaches back to main?
