It should get added to a list (either tcp_active_pcbs or
tcp_listen_pcbs) when you call tcp_connect() or tcp_listen()

Although we don't have a lot of documentation, it would seem that what
we do have is getting out of date.  As you've recently experienced this,
could you highlight the (major) bits that are wrong so we can fix them? 
Any volunteers to do the fixing?

I expect this is related to your pcb list problem.

No, sorry!

Hope that helps,
