Summary: Opensips crashes when publish received for RLS list

Initial Comment:
Version - trunk(5049)
I have tried all sort of following thing to generate core . But it failed to generate core dump.
1.  disable_core_dump is set to no
2. set fork=no and child=no
3. tried to find core dump  at /
4. compiled opensips with the following command
    make mode=debug modules
    echo $?
    make mode=debug prefix=/usr/local/ install
5. OS stinbng46:/# uname -a
Linux stinbng46 2.6.18-staros-v2-20294-deb #1 SMP Mon Jul 14 05:18:18 EDT 2008 i686 GNU/Linux ( With same OS openser created core dump)

Is there any anything I might be missing? please help me to generate core dump , it will be very helpful for debugging.

Hi Anca,
I have tried with latest trunk build (rev 5060), am getting the same
crash.
I have set 'ulimit -c unlimited' also but the line numbers not getting
printed.

Core was generated by `opensips'.

Hi rmnathan,

I have tested myself and got a crash after some time - it was due to a
recent change that I made. I have commited the fix in trunk.
However I am not really sure it is the same as you have seen, as in your
trace there isn't enough information -like line numbers. Can you please
update and test again and report if you see the crash again. 
Btw, have you run: 'ulimit -c unlimited'?

regards,
Anca
