I am receiving a segmentation fault in boost::iterator_property_map for
the following code.
// Prepare Data
infrastructure::Graph_Base::Data_Map_t m_data_map;
// Process Graph
visitor::Graph_Visitor graph_visitor_ref ( *graph_ptr,
&m_data_map );
// Segmentation fault starts here
boost::breadth_first_search
( graph_ptr->get_Graph(), // Grabs the adjacency list
reference
graph_ptr->get_Vertex ( 1 ), // Grabs the first vertex
descriptor
boost::visitor ( graph_visitor_ref ) ); // Call visitor
(line 218)
Here is the backtrace:

I checked the graph_ptr and it appears to be initialized correctly. At
frame #0, the value of 'v' is 0x4. Is there a way to print out more
information to figure out why I am getting a segfault?
Am I asking my questions in the right place? I say that because I have
posted quite a few messages recently with no one responding.
