           Summary: Node sending a packet to itself via 127.0.0.1 aborts
           Product: ns-3
           Version: ns-3-dev
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: major
          Priority: P3
         Component: internet-stack
        AssignedTo: ns-bugs at isi.edu

This simple program included in a python unit test (utils/python-unit-tests.py,
function testSocket):

    def testSocket(self):
        node = ns3.Node()
        internet = ns3.InternetStackHelper()
        internet.Install(node)
        self._received_packet = None

        def rx_callback(socket):
            assert self._received_packet is None
            self._received_packet = socket.Recv()

        sink = ns3.Socket.CreateSocket(node,
ns3.TypeId.LookupByName("ns3::UdpSocketFactory"))
        sink.Bind(ns3.InetSocketAddress(ns3.Ipv4Address.GetAny(), 80))
        sink.SetRecvCallback(rx_callback)

        source = ns3.Socket.CreateSocket(node,
ns3.TypeId.LookupByName("ns3::UdpSocketFactory"))
        source.SendTo(ns3.Packet(19), 0,
ns3.InetSocketAddress(ns3.Ipv4Address("127.0.0.1"), 80)) ## <<<<<<< crash here

        ns3.Simulator.Run()
        self.assert_(self._received_packet is not None)
        self.assertEqual(self._received_packet.GetSize(), 19)


This aborts with:
.......Received packet with erroneous context ; make sure the channels in use
are correctly updating events context when transfering events from one node to
another.
Segmentation fault (core dumped)

To reproduce, just run utils/python-unit-tests.py.
