[OpenSIPS-Users] opensips 3.0.1 segfault

[Антон Ершов]

Hi,
I discovered this situation. my config may not be very correct, but when it
is executed, the opensips falls into segfault.

event_route[E_DLG_STATE_CHANGED] {
...

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;    }

...

}

when I try to get a dialog profile which is not I get this error

ERROR:core:do_action: Failed to get fixups for command <get_dialogs_by_profile>

and after some time opensips falls in segfault
