I am writting an application-level port of the Pastry DHT. The Application main class (properly registered as an NS3 object) has a pointer to a "Pinger" class that handles the distance metric functionality between the nodes. Upon initialization of the Pinger class, a Ptr to the node the application resides on (fetched by GetNode()) is passed to the pinger, and later on used as the "node" argument when creating a socket, inside the pinger, as follows:

Ptr<Socket> currentSocket = Socket::CreateSocket(m_node, TypeId::LookupByName ("ns3::UdpSocketFactory"));


However, upon execution, and when trying to request a socket from the node stack, a "Corrupted double-linked list" error pops up. The GDB backtrace is the following:
