This problem is driving me nuts, and I've discovered it to be more insidious
than simply having, or not having, a namespace. If one simply edits a
pristine libs/graph/examples/connected_components.cpp and changes
  int num = connected_components(G, &c[0], get(vertex_color, G),
dfs_visitor<>() );
to 
  int num = connected_components(G, &c[0] );
the same VC++ error "C1001: INTERNAL COMPILER ERROR" is reported.

When examining the code, I was wondering why the first version of
connected_components() was used, instead of the second one above, which if I
understand things correctly, should be equivalent. Was it to avoid this VC++
bug?

Not having fun today, JohnB
