--- Comment #9 from Alexander Monakov <amonakov at gcc dot gnu.org> ---
The documentation you're pointing to makes the testcase from comment #2
invalid, and I agree that's the right solution (address of a label remains
valid only as long as its containing function has not returned, similar to
automatic variables), but what is going on in comment #0 is still broken,
please don't close this bug.=
