With the PMF connect syntax, slots are invoked on partially destroyed objects

#include <QtCore>

class Object : public QObject
{
    Q_OBJECT
public:
    Object()
    {
        connect(this, &QObject::destroyed, this, &Object::onDestroyed);
        // connect(this, SIGNAL(destroyed()), this, SLOT(onDestroyed()));
    }
private slots:
    void onDestroyed()
    {
        qDebug() << Q_FUNC_INFO;
    }
};

int main(int argc, char **argv)
{
    QCoreApplication app(argc, argv);
    Object o;
}

#include "main.moc"
