Summary: problem with set_advertised_address function in rev #8533

Initial Comment:
Hi,
I've updated my opensips with rev #8533, set_advertised_address function works properly, but I'm making load tests now and there is problem.
I'm using SIPp with default scenario and I've emerged, that after about 1000 calls with call-rate 10(0ms)/1s, opensips crashes with following errors:
DEC 27 13:11:11 opensips /sbin/opensips[2292]: CRITICAL:core:qm_debug_frag: qm_*: prev. fragm. tail overwritten(c0c0c000, abcdefed)[0xb771d158:0xb771d170]!
DEC 27 13:11:12 opensips /sbin/opensips[2288]: CRITICAL:core:qm_debug_frag: qm_*: prev. fragm. tail overwritten(c0c0c000, abcdefed)[0xb771d13c:0xb771d154]!
DEC 27 13:11:12 opensips /sbin/opensips[2291]: CRITICAL:core:qm_debug_frag: qm_*: prev. fragm. tail overwritten(c0c0c000, abcdefed)[0xb771d13c:0xb771d154]!
DEC 27 13:11:12 opensips /sbin/opensips[2294]: CRITICAL:core:qm_debug_frag: qm_*: prev. fragm. tail overwritten(c0c0c000, abcdefed)[0xb771d13c:0xb771d154]!
DEC 27 13:11:13 opensips /sbin/opensips[2312]: CRITICAL:core:receive_fd: EOF on 13 

I'm using command: 
$avp(newvia)=$hdr(Via){via.host}+":"+$sp;
set_advertised_address("$avp(newvia)");
if I delete it, or set ("192.168.1.1"), everything works properly and opensips can handle 3000 calls and more.

Plz help
Jack

Message:
Hello,

It seems you are dealing with a memory corruption.
If you still do all the VIA transformations, but statically set the
advertised address param, do you still get the crashes ?
Like : 

$avp(newvia)=$hdr(Via){via.host}+":"+$sp;
set_advertised_address(192.168.1.1)

Trying to see which ops triggers the actual corruption, the VIA
transformations or the adv address.

Regards,
Vlad
