--- Comment #1 from Reid Kleckner <rnk at google.com> ---
Yes, the key thing here is -O3, which raises the tail duplication threshold,
resulting in the same label being emitted twice. I discussed a plan to fix this
with Amy yesterday.

In the meantime, I might try to put together a workaround to make this not be a
fatal error. Missing one heap allocation site won't be the end of the world.
