[OpenSIPS-Devel] drouting crash

[Антон Загорский]

Hi.

I'm getting drouting module's crash during do_routing call on openSIPS from
svn opensips_1_6 branch revision 7849 (latest)

Cfg snippet:

xlog("*** route[invite]: call do_routing() with RURI [$ru]");
if (!do_routing("1"))
{
	xlog("*** !!! route[invite]: No rules found for do_routing().
STOP");
	send_reply("503", "Drouting");
	exit;
 };

 xlog("*** rout[invite]: do_routing() passed");



Log output:

If I add a new rule with id=2, prefix=9999, groupid=1, then :
1. do_routing with RURI 'sip:999889112599077 at org1.tel.oyster.su' passed
2. do_routing with RURI 'sip:999989112599077 at org1.tel.oyster.su' fails
exactly that way.

As I see from debug the problem is dereferencing invalid pointer
(rt_info->pgwl[0].pgw is 0x1)

GDB backtrace and some debug please see at http://pastebin.com/smTbka3E
