      Description

      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.
