Category: graph Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: Nobody/Anonymous (nobody) Assigned to: Jeremy Siek (jsiek) Summary: remove_edge core dumps on self-circle Initial Comment: This is uncovered while using in bioconductor's RBGL. This is tested on boost_1_33_1 with modified test codes, adjacency_list.cpp: bash-3.00$ cd download/boost_1_33_1/libs/graph/example/ bash-3.00$ diff adjacency_list.cpp bug_remove_vertex.cpp 78a79,81

// test removal of self-circle add_edge(vertex(3, g), vertex(3, g), EdgeProperties("test"), g);

cout << endl << "removing edge (3,3): " << endl; remove_edge(vertex(3, g), vertex(3, g), g);
