The other person is running inside a jail, while I am not. He says: 1. sysctl kern.sugid_coredump=1 is necessary in FreeBSD for the core dumps. My system already has that enabled. 2. He used "-glldb and stopped the exim binary being stripped" - and that is an option passed to gcc. I don't know the equiv for clang. If you'd like to build a version that would coredump, I am happy to give you access to my server for that purpose. -- Best regards, Odhiambo WASHINGTON, Nairobi,KE +254 7 3200 0004/+254 7 2274 3223 "Oh, the cruft.", egrep -v '^$|^.*#' :-) -- ## List details at https://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
