--- Comment #6 from Jonathan Wakely <redi at gcc dot gnu.org> ---
This seems different enough to PR 63151 and PR 66617 to warrant it's own PR.


Reduced:

struct VBase { };

class Base
        : public virtual VBase
{
protected:
        Base(int, int)
        {}
};

struct Derived : Base
{
        Derived()
        :
                Base{1, 1}
        {}
};

Derived myDerived;



x.cc: In constructor ‘Derived::Derived()’:
x.cc:15:12: error: ‘Base::Base(int, int)’ is protected within this context
   Base{1, 1}
            ^
