Re: openldap-2.1.14 + ldapdb.c: slapd core dumped: gdb bt & truss

["Alex Deiter" <tiamat@komi.mts.ru>]

Hello!

I rebuild openldap-2.1.14 without threads (--without-threads), with debug
symbols (-g), and run

# truss -o slapd.truss /usr/local/libexec/slapd -h "ldaps:/// ldap:///
ldapi:///"

# ./server -p 7777
....
# ./client -p 7777 deiter
...

Mar  1 19:07:05 deiter /kernel: pid 19712 (slapd), uid 0: exited on signal
11 (core dumped)
