[Fwd: Re: Haunting free(): invalid pointer 0x8a11604!]

Ok, your problem is that the TCPSession::final calls delete this when
the thread ends.

Your choices are

1) Dont call tcp->detach(), call start()... the thread will be deleted
automaticall by TCPSession::final
2) override virtual void final() in TCPSessionThread, to do nothing.

For the library, TCPSession::final should say if(!isDetached()) delete this;
