--- Comment #2 from Marshall Clow (home) <mclow.lists at gmail.com> ---
This is not a libc++ bug.

The allocator argument for the constructor to std::function must satisfy the
allocator requirements (see func.wrap.func.con/1). 

std::allocator<void>, despite its name, does not satisfy those requirements.
[ Aside: It cannot satisfy those requirements; because it would have to be able
to construct and destroy objects of type `void` ]
