Could you be more specific as to why this is ill-formed? Section 11.1
only specifies that B::B() is a protected member of class B.

11.2 then specifies (in [class.access.base]/1) that this constructor
is still protected in class D. [class.access.base]/4 then specifies
that a member that is protected in a derived class is accessible in
the scope of that derived class.

Therefore, B::B() is accessible within D::f(). I cannot see why the
code above is in error.
