Hello, Thanks for the response. I am deleting vertices that are no longer needed. I have an algorithm that does work each time a vertex is added, so I delete those that are no longer referenced.
Also my graphs definetly do not have self loops. (Nodes that reference them selves right?).
Yes -- edges from a node to itself. Why are you using mutate_graph? That is specific to the Graphviz reader. If you are writing a graph algorithm, you can use clear_vertex and remove_vertex directly. See if that solves the problem. Also, are you sure the entry in bgl_nodes[node] is valid? Your backtrace seems to suggest that it is a null pointer. -- Jeremiah Willcock
