Problem:

class parent
{

public:

<= p>=C2=A0 =C2=A0 virtual int some_method()const{error();}

=C2=A0 =C2= =A0 [[noreturn]] virtual void error()const=3D0;
};


= class child:public parent

{

=C2=A0 =C2=A0 =C2=A0[[noreturn]] vo= id error()const{throw std::runtime_error("Error in class child");= }
};

[[noreturn]] is not a part of error method signature. So,= i have "warning: no return statement in function returning non-void&q= uot; in some_method. Proposal - include [[noreturn]] attribute to function = signature. Sory if my english is bad.
