As a result, copied object is not equal to original one and usually can't be used any more. Here's the data fields that aren't copied: 1. m_graph (is copied only in case the subgraph object represents root subgraph). 2. m_local_vertex and m_local_edge containers (ok for root subgraph, data loss for children subgraphs). The patch with fix is attached." Bugs new To Be Determined graph Boost Development Trunk Problem subgraph
