Apologies, I am using an older version of common c++

In older versions of the library you would use "delete this" for detached threads. In the current (1.3) releases, you should NEVER do this. That final() was appearently leftover from before detach behavior was changed. In 1.?2? and definately 1.3, detach deletes the the thread the object for you after you exit() the thread, and does it through the virtual destructors via the Thread base class.

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;

I would also suggest declaring empty virtual destructors for any inherited classes for which you have no specific
need for a destructor. I dont really know why this should be necessary, but for some reason (at least in the past)
I have found this necessary, and now do it as a habit.
An isolated test-case is definitly the way to go!
Well I just can't get it any simpler than this. Invalid pointer is still
present exactly like before. Am I missing something? Brains?
I am using cc++ 1.3.1, gcc 3.3.3 20040412, Fedora Core 2 (Linux). cc++ was
compiled on this machine. testlistener is the test program.
TCPListener is the one that will create TCPSessionThread per connection when there are connections pending. TCPSessionThread does nothing at all (and the invalid pointer error appears in destructor).
I linked it with -lccgnu2 -ldl (used also -lpthread, but it is not needed
really).
Valgrind gives this when connecting the test program and sending some text
to it:
