[Boost-users] [BGL]: adjacency_list_io bug?

Hello everybody!

I'm using adjacency_list_io to import my graphs from the disk:

  typedef boost::adjacency_list<boost::vecS, boost::vecS,
boost::undirectedS > graph_t;

  graph_t wwwg;

  //string dataFile("www.bdat");
  string dataFile("www_undirected.bdat");

  cout << "importing www network from file \"" << dataFile << "\" ... ";
  ifstream wwwDatIn(dataFile.c_str());
  wwwDatIn >> read( wwwg );
  wwwDatIn.close();

This works nicely with g++ 3.3, but g++ 4.0 refuse to compile this code
and chokes with an error message like

/home/sebi/projects/diplom/src/boost_1_33_1/boost/graph/adjacency_list_io.hpp: In member function 'boost::GraphParser<Graph_t, VertexProperty, EdgeProperty, VertexPropertySubset, EdgePropertySubset>& boost::GraphParser<Graph_t, VertexProperty, EdgeProperty, VertexPropertySubset, EdgePropertySubset>::operator()(std::istream&) [with Graph_t = boost::adjacency_list<boost::vecS, boost::vecS, boost::undirectedS, boost::no_property, boost::no_property, boost::no_property, boost::listS>, VertexProperty = boost::no_property, EdgeProperty = boost::no_property, VertexPropertySubset = boost::no_property, EdgePropertySubset = boost::no_property]':
/home/sebi/projects/diplom/src/boost_1_33_1/boost/graph/adjacency_list_io.hpp:327:   instantiated from 'std::istream& boost::operator>>(std::istream&, boost::GraphParser<Graph, VP, EP, VPS, EPS>) [with Graph = boost::adjacency_list<boost::vecS, boost::vecS, boost::undirectedS, boost::no_property, boost::no_property, boost::no_property, boost::listS>, VP = boost::no_property, EP = boost::no_property, VPS = boost::no_property, EPS = boost::no_property]'

I have no clue where this comes from, but it seems to be some
incompatibility between g++ 4.0 and adjacency_list_io. Would be nice if
someone could enlighten me or fix it.

Thanks!
