Description
Hard crash when closing QUdpSocket or QTcpServer.
Regression caused by Change-Id: Idc75178f7d05057b610ac7000e95486d6a52cb85
qnativesocketengine_winrt.cpp -> void QNativeSocketEngine::close()
hr = d->tcpSocket()->QueryInterface(IID_PPV_ARGS(&socket3));
Will fail and then cause a null pointer deference few lines below with QUdpSocket.
hr = socket3->CancelIOAsync(&action);
Or with QTcpServer (tcpListener) it will trigger ASSERT since CancelIOAsync is not a supported action for StreamSocketListener.
hr = QWinRTFunctions::await(action);
See patch for possible fix by excluding this code path to QTcpSocket only.
