I have observed the following behavior using the remove_edge function and am curious if anyone else has seen this.

remove_edge(edge_descriptor, graph) // occasionally fails in a seemingly indeterminant way

remove_edge(source(edge_descriptor, graph), target(edge_descriptor, graph), graph) // works fine

It sounds like either the edge_descriptor is getting invalidated or there is a bug somewhere in remove_edge.

The adjacency list I am using is listS listS, and this is not an issue with invalid edge_iterators, i.e. I collect all the edge_descriptors to be removed before removing them.

Are you sure that there are no duplicate edge descriptors?

I can provide more detailed info upon request.

We won't be able to help without more detailed information. Doug
