Error Type: Segmentation fault
Description: In the current implementation of the acceptor pattern, in the nocontrol/ofp-control folder, the code crashes when the connection between the switch and the freeflow controller(nocontrol) is closed by the switch.
Location : freeflow/sys/reactor.ipp, line 40("delete h")
Code Snippet :
inline void
Reactor::remove_handler(Event_handler* h) {
timers_.cancel(h);
handlers_.remove(h);
if (h->has_flags(HANDLER_IS_OWNED)
delete h; // <-- line 40
}
Reason: The handler object has already been deleted in the nocontrol/ofp-control/openflow.cpp:line 60(on calling the on_close method)
