Ah ha! You want:

Graph& tSubGraph = g.create_subgraph();

The root graph actually allocates a new child in its own memory space in
create_subgraph(), and then gives you a reference to the subgraph. What's
happening here is that subgraph is getting double-freed. Yes, we should do
something to protect against this.
