It looks like a broken assumption in the design of labeled_graph
(which is mostly experimental), that any use of integral labels would
be in the range [0, num_vertices(g)). When you insert a new label, it
is automatically resizing the container to accommodate your new label.
You may be better off not using labeled_graph.
