See [temp.arg.nontype]p3
<https://timsong-cpp.github.io/cppwp/n4868/temp.arg.nontype#3>:
> For a non-type template-parameter of reference type, or for each non-static
> data member of reference or pointer type in a non-type template-parameter
> of class type or subobject thereof, the reference or pointer value shall

And "f_{a_}" is initializing the pointer as a subobject of a temporary
object, so this is invalid. Though the error given might be wrong or
misleading.
