Hi guys. I'm using pjlib v1.5.
My application handles network events. When network dissapears, i unregister
all accounts and delete buddies from the lib by using
pjsua_buddy_del(pjsua_buddy_id).
When network appears, i reregister accounts and add buddies by
pjsua_buddy_add(pjsua_buddy_config,pjsua_buddy_id). Everything was fine when
i was using pjlib 1.4.5,
but in the new version there are problems.
1) After i removed buddies and unregistered accounts, I got next warning in
Xcode after few seconds (in debug this is not a crash, in release i didn't
try to run, just in case):
malloc: *** error for object 0x18d2200: double free

2) When i'm trying to add buddies back, application crashes:

In pop_freelist function:
// The freelist values in the <timer_ids_> are negative, so we need
// to negate them to get the next freelist "pointer."
ht->timer_ids_freelist = -ht->timer_ids[ht->timer_ids_freelist]; // <--
crashes here, ht is not NULL
3) If i dont use adding/deleting, but call
pjsua_buddy_update_pres(pjsua_buddy_id) when network appears, i dont get
online status for buddies in callback from the lib (status is
PJSUA_BUDDY_STATUS_UNKNOWN).
Maybe i could help with additional info, just tell me what u need.
