8250,Bug deleting self loop edges in parallel code,Borja Miñano <bminyano@…>,ngedmond,"Hello, 

I think I found a bug in the graph parallel library. 
I have a bidirectional adjacency list which has some self loop edges. 
When I try to delete them with remove_edge_if (or remove_out_edge_if or remove_in_edge_if) the edges are deleted, but it seems that some reference gets broken in the graph. 
If I iterate over the in_edges a reference to a self loop is found. But it does not happen if I iterate over the out_edges. 
If the graph is written in a graphviz file the self loop edges does not appear. 

I think there is some broken reference into the adjacency list that keeps the in_edges. 

I have two different pieces of code (one with pbgl and the other with bgl). They do the same, create a graph, delete the self-edges and print the in_edges. 

Could someone have a look at this problem?
