Dear all, I get a crash when copying a graph. Probably something simple. Does anyone know? void Foo() { typedef boost::adjacency_list<boost::listS, boost::listS, boost::bidirectionalS, boost::property<boost::vertex_index_t, int> > Graph; Graph graph1; Graph graph2; FillGraph(&graph1); //normal copy boost::copy_graph(graph1, graph2); //<-- } Wkr, me
