Line 110 seems correct, but the part of the Graph object at offset 8 is never initialized for some reason, if I read Valgrind's output correctly.
All that Graph object has is a Graph_t object and a IdVertexMap_t object. They are part of object. class Graph { public: typedef property< vertex_index_t, uint32_t, property< vertex_name_t, boost::shared_ptr<Component> > > VertexProperty_t; typedef adjacency_list<setS, // OutEdgeList setS, // VertexList directedS, // Directed VertexProperty_t> // VertexProperties Graph_t; typedef std::map<uint32_t, Vertex_t> IdVertexMap_t; Graph(){} ... Missing accessor functions for adding, retrieving or deleting Component objects ... Graph_t m_graph; IdVertexMap_t; } I don't initialize these objects in the constructor since both are objects that should be okay as empty containers. Stephen
