--- Comment #7 from Paul Robinson <paul_robinson at playstation.sony.com> ---
Thanks for pointing this out, Reid!  Yes, we trip over it, in <tuple>,
I just hadn't noticed it yet.

My most recent Clang update is based on r222093, and it gets caught by this.
I patched it with r222471, which didn't help; once you get done with macro
expansion we have the token sequence
  noexcept(noexcept(swap(declval<sometype&>(), declval<sometype&>())) && ....
in the exception-specification for tuple::swap(tuple&).  At least I think
it's tuple::swap(), sometimes this template stuff is hard for me to parse.

Anyway, it's still a problem for us.
