will help you It appears you're treating warnings as errors and Boost currently has an outstanding issue where BOOST_STATIC_ASSERT causes a warning on GCC and Clang:

wish help you to fix your issue I have some C++ code, and for some reason, for a couple of classes, they show up as boost::boost::boost::boost::boost::classname in the Visual Studio browser. , I installed boost 1.40 instead of 1.39, and the problem went away.
Boost graph unable to union_set

Boost graph unable to union_set

wish of those help I've figured it out thanks to this tutorial: Algorithm for selecting all edges and vertices connected to one vertex
The problems was:
code :
using namespace boost;

typedef adjacency_list <vecS, vecS, undirectedS, cv::Point> Graph;
typedef graph_traits<Graph>::vertex_descriptor Vertex;
typedef graph_traits<Graph>::vertices_size_type VertexIndex;

int main()
    Graph graph;

    graph_traits<Graph>::edge_descriptor edge;
    bool flag;

    std::vector<Vertex> verticesVector;
    Vertex verticesTable[8];
    std::vector<cv::Point> points;


    int i = 0;
    for(std::vector<cv::Point>::iterator it = points.begin(); it != points.end(); it++, i++)
        verticesTable[i] = add_vertex(graph);
        graph[verticesTable[i]].x = (*it).x;
        graph[verticesTable[i]].y = (*it).y;

    std::vector<VertexIndex> rank(num_vertices(graph));
    std::vector<Vertex> parent(num_vertices(graph));

    typedef VertexIndex* Rank;
    typedef Vertex* Parent;

    disjoint_sets<Rank,Parent> ds(&rank[0], &parent[0]);


    typedef component_index<VertexIndex> Components;
    Components components(parent.begin(), parent.end());

    Graph::vertex_iterator vertexIt, vertexEnd;
    boost::tie(vertexIt,vertexEnd) = vertices(graph);
    for(;vertexIt != vertexEnd; ++vertexIt)
        Vertex a = *vertexIt;
        cv::Point &b = graph[a];
        std::cout<<"Point: "<<b.x<<";"<<b.y<<std::endl;

    boost::tie(edge,flag) = add_edge(verticesTable[0],verticesTable[1],graph);
    boost::tie(edge,flag) = add_edge(verticesTable[1],verticesTable[2],graph);
    //boost::tie(edge,flag) = add_edge(verticesTable[2],verticesTable[3],graph);
    boost::tie(edge,flag) = add_edge(verticesTable[3],verticesTable[4],graph);
    boost::tie(edge,flag) = add_edge(verticesTable[1],verticesTable[5],graph);
    boost::tie(edge,flag) = add_edge(verticesTable[5],verticesTable[6],graph);
    boost::tie(edge,flag) = add_edge(verticesTable[6],verticesTable[7],graph);

    BOOST_FOREACH(Vertex current_vertex, vertices(graph)) 
        std::cout<< "representative["<<current_vertex<<"] = "
        << ds.find_set(current_vertex)<<std::endl;


    Components components2(parent.begin(), parent.end());

    BOOST_FOREACH(VertexIndex current_index, components2)
        std::cout<<"component "<<current_index<<" contains: ";
        BOOST_FOREACH(VertexIndex child_index, components2[current_index])
              std::cout<<child_index<<" "<<" x,y = "<<graph[verticesTable[child_index]].x<<";"<<graph[verticesTable[child_index]].y<<"||";

    //write_graphviz(std::cout, graph);


    return 0;

hope this fix your issue The following compiles under VS2010 (Express) but not gcc (4.6.2 here). , Your move constructor declares its parameter const:
code :
inline LockedProxy(const LockedProxy && other)
inline LockedProxy(LockedProxy && other)

Does that help Good time of day! , Fix your variant type:
code :
typedef boost::variant<
            boost::recursive_wrapper<boost::tuple<ParsedThunk, ParsedThunk> >
        > ParsedThunkEntity;

Any of those help Yes, it should be possible. The problem can be two-fold: your code or Boost graph code. (Problem in Boost.Serialization is less likely).
First of all, reduce the problem -- exclude your custom stream.
code :
ar >> serialization::make_nvp("graph_property", 
                    get_property(graph, graph_all_t()) );
#include <boost/graph/adj_list_serialize.hpp>
#include <boost/serialization/serialization.hpp>

struct vertex_data_t
    typedef boost::vertex_property_tag kind;
typedef int ObjectType;
typedef boost::property<vertex_data_t, ObjectType > Property;
typedef boost::adjacency_list<boost::vecS, boost::vecS, 
                 boost::bidirectionalS, Property> AdjList;

BOOST_CLASS_VERSION(AdjList, 1); //default is 0, corresponds to files 
                                 //serialized with Boost 1.48

namespace boost {

namespace serialization {

template<class Archive>
inline void load(
    Archive & ar,
    AdjList &graph,
    const unsigned int file_version
  typedef AdjList Graph;
  typedef typename graph_traits<Graph>::vertex_descriptor Vertex;
  typedef typename graph_traits<Graph>::edge_descriptor Edge;

  unsigned int V;
  unsigned int E;

  std::vector<Vertex> verts(V);
  int i = 0;
  while(V-- > 0){
    Vertex v = add_vertex(graph);
    verts[i++] = v;
    ar >> serialization::make_nvp("vertex_property", 
                                  get(vertex_all_t(), graph, v) );
  while(E-- > 0){
    int u; int v;
    Edge e; bool inserted;
    boost::tie(e,inserted) = add_edge(verts[u], verts[v], graph);
    ar >> serialization::make_nvp("edge_property", 
                                  get(edge_all_t(), graph, e) );
  if (file_version>=1)
      ar >> serialization::make_nvp("graph_property", 
                                     get_property(graph, graph_all_t()) );
