Simple boost program throws exception

I'm trying boost for the first time on Codewarrior 8.0 for windows. 
The Boost version is 1.25.1 from the "Boost Graph Library" 
accompanying CD. The offensive code is :

#include <boost/config.hpp>
#include <iostream>

#include <boost/graph/adjacency_list.hpp>

using namespace boost;
using namespace std;

int main()
{
          typedef adjacency_list<vecS,vecS,directedS,
    property < vertex_name_t, char >,property<edge_weight_t,double>  
> Graph;
    
        property_map < Graph, vertex_name_t >::type    name_map ;
        property_map < Graph, edge_weight_t >::type    value_map ;

        Graph g;

        typename graph_traits<Graph>::vertex_descriptor a,b;
        
        a = add_vertex(g);	name_map[a] = 'a';
        b = add_vertex(g);	name_map[b] = 'b';
        
        typename graph_traits<Graph>::edge_descriptor ed;
        bool inserted;
        
        tie(ed, inserted) = add_edge(a, b, g);	
        value_map[ed] = 1.2;

        return 0;
}

If the second template parameter for class VertexListS is replaced 
with listS it compiles and run normally.

         typedef adjacency_list<vecS,listS,directedS,
    property < vertex_name_t, char >,property<edge_weight_t,double>  
> Graph;

Can you please advise why? 

Best Regards
