--- Comment #12 from Jeffrey A. Law <law at gcc dot gnu.org> ---
So this is probably still an issue given we're not supposed to use lock-free
and locked sequences simultaneously on any given object.  However, given this
only affects us when we don't have the "A", c#2 and c#3 I'm deferring this
indefinitely.
