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.
