Re: (ITS#6455) Able to crash slapd while using back_ldap

[j@gropefruit.com]

I am currently in debug mode with slapd-dbg 2.4.20:

Having run these commands:

sudo gdb
handle SIGPIPE nostop=20
handle SIGPIPE noprint
file /usr/sbin/slapd
set args -d -1 -u openldap -g openldap -h ldapi:/// ldaps:/// ldap:/// =
-f /etc/ldap/slapd.conf
run

Once it crashes, I will be running:

thr apply all bt

After which I will upload the coredump to your FTP server.
