Probably related: Code like

#include <boost/graph/adjacency_list.hpp>
using namespace boost;
typedef property<vertex_bundle_t, int> nodeProp;
typedef adjacency_list<vecS, vecS, bidirectionalS, nodeProp> graphType;
graphType graph;  // gives compiler error with 1.51.0

compiles with Boost 1.50.0 but does not with 1.51.0 (using clang 3.1).

Creating a property named vertex_bundle will confuse the compiler, since there is a built-in property in adjacency_list by that name already. The original code will take a bit more work to fix. As a workaround, could you try putting in an explicit cast to int Vertex::* on &Vertex::base_value? That worked for me.

Two lawmakers have filed fake handbags bills to legalize the half-gallon jugs, but a group of beer distributors is fighting both measures and appears to have helped cheap louis vuitton damier ebene canvas effectively kill both for the year. The half-gallon size growlers are an industry standard and are sold at christian louboutin outlet breweries around the country.
