   Storing leda::graph::nodes in STL containers
  I want to be able to access nodes in a parametrised leda::graph by their external information.For example, let's say I have a geographical map, and I want to access the leda::graph::node with the name "France" in order to use it as a starting point in a travel route algorithm. Then I need a way to map strings to node's. But LEDA does not provide a way to do this. It's not possible to index the graph by a node's external info or it's ID.The obvious solution would be to create a std::map<std::string, leda::graph::node> for doing just that. But whenever I try to store nodes (or pointers to them) in an STL container, I get a linkage error like this one: "error LNK2001: unresolved external symbol __imp___CrtDbgReportW"Everything else is working correctly, and I have no idea what the reason of the error would be. My own guess at this point is that the node data structure is implemented in a way which makes it impossible to store them in STL containers for some reason.Can anyone help?   
  It doesn't work with STL, but it does work fine with LEDA's own containers. (Should have tried this a lot earlier!)Still, it's curious why it didn't work with STL.
