Comment (by endecotp):

 The fixed version still seems wrong.  Consider a vertex in an undirected
 graph with only self-loops.  The current code will do nothing inside the
 loop, and then clear the out_edge_list.  The problem is that m_edges has
 not been updated to remove these edges.  When I subsequently iterate over
 all the edges in the graph, I still find these edges (and then crash).

 This is the first time that I've ever used Boost.Graph so it's possible
 that I'm misunderstanding something...
