     Type:  Bugs                    |      Status:  new    
Milestone:  Boost 1.38.0            |   Component:  None   
  Version:  Boost 1.37.0            |    Severity:  Problem
 Keywords:  graph dimacs            |  
------------------------------------+---------------------------------------
 There two problems I noticed using read_dimacs_max_flow :

 1. First, at the end of the parsing loop, a conditional test is done :
  if ( feof (stdin) == 0 ) /* reading error */
     { err_no=EN21; goto error; }
 As the loop is dealing with "std::istream& in=std::cin" I assume it's a
 mistake.

 2. "capacity" and "reverse_edge" are not referenced
 int read_dimacs_max_flow(Graph& g,
                          CapacityMap capacity,
                          ReverseEdgeMap reverse_edge,
                          typename graph_traits<Graph>::vertex_descriptor&
 src,
                          typename graph_traits<Graph>::vertex_descriptor&
 sink,
                          std::istream& in=std::cin)

 3. Even with documentation examples I have this message :
 malloc: *** error for object 0x1000f4: Non-aligned pointer being freed
