If you stuck 'static' to the local scope declarations that ought to fix
it too.  The main problem is that without 'static', there will be a
hidden context pointer in the struct that points to the main's local
scope. This can't work with RBTree because it cannot obtain a pointer to
this local scope when it needs to create new nodes.
