Hi,
Line 189 of subgraph.hpp is:
return std::make_pair((*i).second, i != m_local_vertex.end());
Consequently iterator i is dereferenced even when it is equal to m_local_vertex.end(). So here comes a patch. When *i is not valid, the patch simply returns u_global (the closest vertex_descriptor available to the code), another value may make better sense (but since the value is not supposed to be used).
You could use graph_traits<Graph>::null_vertex() to get a real "null" vertex. Thanks for the patches! I'm hitting the road right now, but I'll get to them tomorrow night if nobody gets there first. Doug
