Description
The move constructor of a std::promise
object does not need to allocate any memory, so the
move-construct-with-allocator overload of the constructor
is superfluous.
Suggestion
Remove the constructor with the signature template <class
Allocator> promise(allocator_arg_t, const Allocator&
a, promise& rhs);
Notes
Create an issue. Detlef will look into it. Will solicit feedback from Pablo. Note that "rhs" argument should also be an rvalue reference in any case.
