clang rejects this code with a similar error message as gcc.

--- Comment #4 from Jonathan Wakely <redi at gcc dot gnu.org> ---
The standard is clear that D::D(int) is protected:
"Base-class constructors considered because of a using-declarator are
accessible if they would be accessible when used to construct an object of the
base class; the accessibility of the using-declaration is ignored."
So G++ is correct to give an error on that line.
I'm not sure why D::D() is public though. It seems that it isn't inherited from
B::B() but is implicitly defined by the compiler (and then calls B::B() but
it's OK for D's constructor to call the protected constructor of its base
class).

--- Comment #5 from Jonathan Wakely <redi at gcc dot gnu.org> ---
The standard says:
"If there is no user-declared constructor for class X, a non-explicit
constructor having no parameters is implicitly declared as defaulted"
An inherited constructor is not user-declared, so D still gets an
implicitly-declared:
D() = default;
This is public, and can call the protected B() constructor.
So G++ is correct.
