You mean apply the patch attached to STDCXX-1070? It looks good
to me. I also checked the test. It's odd that the problem didn't
get caught sooner (we did get errors when the function templates
were declared static, which is why the static keyword is commented
out). But it sure does look like a problem.

FWIW, if you want quick input on a patch, I find it easier when
it's posted to the list (instead of attaching it to the issue).
Attaching it is useful when it's large and/or when you don't
have commit permissions. Others may have a different preference.
