File res/res_pjsip_pubsub.c:

PS8, Line 1254: 	ast_debug(3, "Destroying subscription tree %p '%s->%s'\n",
              : 		sub_tree, ast_sorcery_object_get_id(sub_tree->endpoint), sub_tree->root->resource);
A destructor needs to be tolerant of a partially constructed object.  You may not have a sub_tree->endpoint or sub_tree->root set.


Line 1527: 				ao2_ref(sub_tree, -1);
I think this unref should not be here.  It certainly wasn't part of the push_task success or failure before.


Line 3636: 		ao2_cleanup(sub_tree);
Alternate exit needs to not cleanup sub_tree.

i.e., left over ao2_cleanup


PS8, Line 3660: 	ast_debug(3, "sub_tree %p sub_tree state %s\n", sub_tree,
              : 		(sub_tree ? sub_tree_state_description[sub_tree->state] : "UNKNOWN"));
This is redundant with the same message in pubsub_on_refresh_timeout().
