      Why this code, running repeatedly in a custom object moved to QThread instance, produces memory leak?

      void QCustomHTTPManager::compare()
{
    // custom code to create request and  multiPart content
    QNetworkReply *reply = networkaccessmanager->post(request,&multiPart);
    connect(reply,&QNetworkReply::finished,eventloop,&QEventLoop::quit);
    eventloop->exec();
    emit compared();
    reply->deleteLater();
}

      No leak when change to this:

      void QCustomHTTPManager::compare()
{
     // custom code to create request and  multiPart content
    QTimer::singleShot(1,loop,&QEventLoop::quit);
    eventloop->exec();
    emit compared();
}
