      A check is needed as follows:

      qtbasesrcopenglqgl.cpp:162
      
Q_GLOBAL_STATIC(QGLSignalProxy, theSignalProxy)
QGLSignalProxy *QGLSignalProxy::instance()
{
    QGLSignalProxy *proxy = theSignalProxy();
    if (proxy && qApp && proxy->thread() != qApp->thread()) {
        if (proxy->thread() == QThread::currentThread())
            proxy->moveToThread(qApp->thread());
    }

      Please note the extra "&& qApp". Without this, we see a crash on exiting the app. This has been fixed in 5.5.0.
