With the following source, we get a nice little illustrative error:
the second use of the `retry' label in a *different* function causes
confusion in the template instantiation mechanism.  In essence, the
fact that we're reusing the label name leads to an unresolved
`reference' to the first label after the second label is properly
resolved.  Changing the name of the label in resize() to retry2 solves
the problem and generates correct code.
