[OpenSIPS-Users] segfault in dialog.so

[Антон Ершов]

Hello friends,
I already wrote about this problem and there was no answer.
http://lists.opensips.org/pipermail/users/2019-October/041771.html
I still want to process call profiles in event_route, but opensips falls
into error at the same time.

opensips -V

my event_route

event_route[E_DLG_STATE_CHANGED] {
    xlog("L_INFO", "[$param(callid)] - new state dialog changed
$param(new_state) old state $param(old_state) \n");

    cache_raw_query("redis:group3", "HGET callid
$param(callid)","$avp(reknum)");
    if ($avp(reknum) != NULL) {
        xlog("L_INFO", "[$param(callid)] - get reknum $avp(reknum) \n");

if ( get_dialogs_by_profile("reknumber", $avp(reknum), $avp(dlg_jsons),
$avp(callcount)) ) {
   xlog("L_INFO", "[$param(callid)] - advertising number  $avp(reknum) has
$avp(callcount) other calls \n");
} else {
   xlog("L_INFO", "[$param(callid)] - this profile does not have active
dialogs \n");
   $avp(callcount) = 0;
}

switch($param(new_state)) {
   case 4:
xlog("L_INFO", "[$param(callid)] - write in REDIS \"callcount $avp(reknum)
$avp(callcount) \n");
if ($avp(reknum) != "" && $avp(callcount) != "") {
   cache_raw_query("redis:group3","HSET callcount $avp(reknum)
$avp(callcount)");
   cache_raw_query("redis:group3","EXPIRE callconut 360");
   xlog("L_INFO", "[$param(callid)] - call established. Now on number
$avp(reknum) $avp(callcount) calls \n");
}
break;
   case 5:
xlog("L_INFO", "[$param(callid)] - write in REDIS \"callcount $avp(reknum)
$avp(callcount) \n");
if ($avp(reknum) != "" && $avp(callcount) != "") {
   cache_raw_query("redis:group3","HSET callcount $avp(reknum)
$avp(callcount)");
   cache_raw_query("redis:group3","EXPIRE callcount 360");
   xlog("L_INFO", "[$param(callid)] - call end. Now on number $avp(reknum)
$avp(callcount) calls \n");
   cache_raw_query("redis:group3","HDEL callid $param(callid)");
}
break;
}
    } else {
        xlog("L_INFO", "[$param(callid)] - reknum vareable is NULL");
        exit;
    }
}

when we try to get a profile of an already dead dialog opensips falls.
please tell me is it possible to implement what I want or is it worth
looking for another solution?
