[Boost-users] [bgl] Problem with topological_sort

Hello,

When I run the example code of topo_sort.cpp in the BGL examples folder, 
it works perfectly. However, if I replace in this example:

   typedef adjacency_list<vecS, vecS, directedS,
     property<vertex_color_t, default_color_type> > Graph;

By:

   typedef adjacency_list<listS, listS, directedS,
     property<vertex_color_t, default_color_type,
                property<vertex_index_t, int > >
   > Graph;

It compiles, but during execution, some assert occurs. This assert 
occurs deep within my std::vector implementation (msvc8.0), in the call 
stack, the latest reference to boost is
 >	TopoSort.exe!boost::iterator_property_map<std::_Vector_iterator<enum 
boost::default_color_type,std::allocator<enum boost::default_color_type> 
 >,boost::adj_list_vertex_property_map<boost::adjacency_list<boost::listS,boost::listS,boost::directedS,boost::property<enum 
boost::vertex_color_t,enum 
boost::default_color_type,boost::property<enum 
boost::vertex_index_t,int,boost::no_property> 
 >,boost::no_property,boost::no_property,boost::listS>,int,int const 
&,enum boost::vertex_index_t>,enum boost::default_color_type,enum 
boost::default_color_type &>::operator[](void * v=0x00355eb8)  Line 349 
+ 0x67 bytes	C++

Or, for people who don't read msvc on a daily basis, it indicated the 
line 350 of property_map.cpp :

/*template<...> class iterator_property_map : ... { */
     inline R operator[](key_type v) const { return *(iter + get(index, 
v)) ; }

Does anybody have any idea of what the problem might be ?

Best regards,
