Looking at the handle that memory for the handle that was destroyed, it
appears the ref count is active, but the handle is no longer on the
nua->nua_handles list.
Here is a listing of the handle's parameters:
(gdb) p *(nua_handle_t *)0x10b5abb8
$1 = {nh_home = {{suh_size = 140, suh_blocks = 0x10b5ae38, suh_lock =
0x10b5acc8}}, nh_next = 0x0, nh_prev = 0x0,
nh_nua = 0x10b58170, nh_valid = 0x0, nh_magic = 0x3002b008, nh_tags =
0x10b5ac48, nh_ptags = 0x0, nh_identity = 0x0,
nh_prefs = 0x10b5b260, nh_special = nua_i_error, nh_has_invite = 0,
nh_has_subscribe = 0, nh_has_notify = 0,
nh_has_register = 0, nh_active_call = 0, nh_hold_remote = 0,
nh_ref_by_stack = 1, nh_ref_by_user = 1, nh_init = 1,
nh_used_ptags = 1, 0, nh_ds = {{ds_usage = 0x0, ds_cr = 0x0, ds_sr =
0x0, ds_route = 0, ds_terminated = 0, ds_has_session = 0,
ds_has_register = 0, ds_has_publish = 0, ds_got_referrals = 0, 0,
ds_has_events = 0, ds_has_subscribes = 0,
ds_has_notifys = 0, ds_local = 0x10b5ac58, ds_remote = 0x10b5ccb0,
ds_leg = 0x0, ds_remote_tag = 0x0, ds_remote_ua = {{
nr_allow = 0x0, nr_accept = 0x0, nr_require = 0x0,
nr_supported = 0x0, nr_user_agent = 0x10b5f600}}}},
nh_auth = 0x10b5dba8, nh_soa = 0x0, nh_referral = {{ref_handle = 0x0,
ref_event = 0x0}}, nh_notifier = 0x0}
Maybe something changed in reference counting...
Here is the nua agent parameters:
(gdb) p *(nua_t *) 0x10b58170
$2 = {nua_home = {{suh_size = 188, suh_blocks = 0x10b58b20, suh_lock =

0x10b57eb0}}, nua_nw_changed = 0x0,
nua_callback = 0x10035764 <sipcb>, nua_magic = 0x0, nua_current =

nua_shutdown_final = 0, 280333376, nua_args = 0x10b58c40, nua_from =
{{a_common = {{h_succ = 0x0, h_prev = 0x0,
h_class = 0x101258f8, h_data = 0x0, h_len = 0}}, a_next = 0x0,
a_display = 0x10b5aac8 "", a_url = {{url_pad = "\000",

url_host = 0x10b5aac9 "10.1.64.123", url_port = 0x0, url_path

url_headers = 0x0, url_fragment = 0x0}}, a_params = 0x0,
a_comment = 0x0, a_tag = 0x0}}, nua_registrations = 0x10b5a620,
nua_invite_accept = 0x10b592e0, nua_root = 0x10a1fb98, nua_server =
{{sut_port = 0x10b580e8, sut_root = 0x10a1fb98}},
nua_nta = 0x10b59348, nua_timer = 0x10b58ca8, nua_sip_parser = 0x0,
nua_shutdown = 0, nua_service_route = 0x0,
nua_media_enable = 0, 280333544, nua_handles = 0x10b58ce8,
nua_handles_tail = 0x10b58cf4}
I hope this helps.
