    Description

      I've seen several crashes related to this in user code, e.g.:

      • Code deleted a QLocalSocket in a slot connected to the QLocalSocket's readChannelFinished().
      • Similar situations often arise with QNetworkReply and its finished() signal.

      Maybe we can have some code that is only enabled in debug mode that warns the user and suggests deleteLater(), e.g.:
      Q_WARN_IF_DELETED_IN_SIGNAL_EMISSION(QNetworkReply, SIGNAL(finished())
