Sure thing! This is the sample graph I've created, using the code at the end of this message: 

Here are a couple of observations:

1. get_in_neighbours() worked fine prior to purging the edges.  2. But once the edges are purged, the problem arises. Vertex 2, 3 and 4 should all have in neighbor 5, but g.get_in_neighbour(v) returns their own vertex index.  3. get_in_edges() is working as intended. 

Thanks for the example. As it turns out this is a bug that occurs only for filtered graphs. I have now fixed it in git. Best, Tiago -- Tiago de Paula Peixoto <tiago@skewed.de>
