      With the Xcode 13.3 toolchain there seems to be a lot of warnings like this, both with Qt 5 and Qt 6:

      qtdeclarative/src/qml/qml/ftw/qintrusivelist_p.h:248:69: warning: performing pointer subtraction with a null pointer may have undefined behavior [-Wnull-pointer-subtraction]
    return (N *)((char *)node - ((char *)&(((N *)nullptr)->*member) - (char *)nullptr));
                                                                    ^ ~~~~~~~~~~~~~~~
