Trying to get Varnish to create a core dump

I am using the production rpm of varnish (not building via the varnish
source) but my VCL has a lot of inline C and I also load a dynamic loadable
library in vcl_init which does has full symbol table, debug on. I keep
getting segmentation faults but cannot get a core file from Varnish to save
my life.
/var/log/kern clearly shows varnish segfaulting
I have tried:
ulimit -c unlimited
echo 1 > /proc/sys/kernel/core_uses_pid
echo 2 > /proc/sys/fs/suid_dumpable
mkdir /mnt/cores
chmod 777 /mnt/cores
echo /mnt/cores/core > /proc/sys/kernel/core_pattern
Anything else that I am overlooking?
Thanks
