Description Tommaso Pecorella 2016-01-14 11:34:56 UTC

Packet::CreateFragment discards the NixVector data. As a result, the fragment causes Nix to raise an assert.
The obvious solution is to copy them:

  Ptr<Packet> ret = Ptr<Packet> (new Packet (buffer, byteTagList, m_packetTagList, metadata), false);
  ret->SetNixVector (GetNixVector ());
  return ret;
