Subject: [boost] Debug Assertion Failed while trying to use read_graphviz

Hello,
I tried to compile and run in VS 2008 the following example illustrating how
to use read_graphviz() function:
#include <boost/graph/graphviz.hpp>
#include <boost/graph/adjacency_list.hpp>
#include <string>
#include <sstream>
using namespace boost;
using namespace std;
int main() {
// Vertex properties
typedef property < vertex_name_t, std::string,
property < vertex_color_t, float > > vertex_p;
// Edge properties
typedef property < edge_weight_t, double > edge_p;
// Graph properties
typedef property < graph_name_t, std::string > graph_p;
// adjacency_list-based type
typedef adjacency_list < vecS, vecS, directedS,
vertex_p, edge_p, graph_p > graph_t;
// Construct an empty graph and prepare the dynamic_property_maps.
graph_t graph(0);
dynamic_properties dp;
property_map<graph_t, vertex_name_t>::type name =
get(vertex_name, graph);
dp.property("node_id",name);
property_map<graph_t, vertex_color_t>::type mass =
get(vertex_color, graph);
dp.property("mass",mass);
property_map<graph_t, edge_weight_t>::type weight =
get(edge_weight, graph);
dp.property("weight",weight);
// Use ref_property_map to turn a graph property into a property map
boost::ref_property_map<graph_t*,std::string>
gname(get_property(graph,graph_name));
dp.property("name",gname);
// Sample graph as an std::istream;
std::istringstream
gvgraph("digraph { graph [name=\"graphname\"] a c e [mass = 6.66] }");
bool status = read_graphviz(gvgraph,graph,dp,"node_id");
return 0;
}
When I run the program I get the Debug Assertion Failed message (when I
delete the line with read_graphviz everything is OK). Could you please help
me with this problem?
Thank you,
Anna.
