[Kamailio-Users] Kamailio Core Dumping

[Stagg Shelton]

I believe that we have discovered why kamailio was core dumping.  We  
received a 200 OK with SDP back from an upstream that had a mal  
formatted Record-Route: header field.

Record-Route: <sip:8.17.32.37;lr=on;did=87e.7defc835>,SUBSCRIBE,NOTIFY

Each time we received one of these packets with the bad RR header,  
openser-1.3.4, kamailio-1.5.1, and SVN kamailio from 6/12 each core  
dumped at update_dialog_dbinfo.  While I understand that the Record- 
Route example is bad, and certainly doesn't conform to the RFC.  Would  
it be possible to do some kind of sanity check on the header and  
handle the garbage data error more gracefully?

Thanks
Stagg
