> In tcptls.c, a client tcptls_session is allocated in ast_tcptls_client_start().  The session is created using ao2_alloc() which returns an ao2 object containing the data as well as a single reference.  In that same function an additional reference is given to the tcptls_session right before the handle_tls_connection() function is called.  The handle_tls_connection() function does not handle this reference at all, except for dereferencing the tcptls_session in one error case, so it doesn't appear the extra ref is necessary.  This results in a memory leak in chan_sip for every new client tcptls_session.
