Everything is in the title:
slapd on master branch segfaults at first connection establishment with an LDAP
client
slapd-2.5.X-Devel
Compilation options:
./configure --prefix=/usr/local/openldap --libdir=/usr/local/openldap/lib64
--enable-overlays --enable-modules --enable-dynamic=yes --with-tls=openssl
--enable-debug --with-cyrus-sasl --enable-spasswd --enable-ppolicy
--enable-crypt --enable-ldap -enable-slapi --enable-meta --enable-sock
--enable-wrappers --enable-rlookups
using default slapd.conf file:
#
# See slapd.conf(5) for details on configuration options.
# This file should NOT be world readable.
#
include /usr/local/openldap/etc/openldap/schema/core.schema
# Define global ACLs to disable default read access.
# Do not enable referrals until AFTER you have a working directory
# service AND an understanding of referrals.
#referral ldap://root.openldap.org

# Load dynamic backend modules:
# modulepath /usr/local/openldap/libexec/openldap
# moduleload back_mdb.la
# moduleload back_ldap.la
# Sample security restrictions
# Require integrity protection (prevent hijacking)
# Require 112-bit (3DES or better) encryption for updates
# Require 63-bit encryption for simple bind
# security ssf=1 update_ssf=112 simple_bind=64
# Sample access control policy:
# Root DSE: allow anyone to read it
# Subschema (sub)entry DSE: allow anyone to read it
# Other DSEs:
# Allow self write access
# Allow authenticated users read access
# Allow anonymous users to authenticate
# Directives needed to implement policy:
# access to dn.base="" by * read
# access to dn.base="cn=Subschema" by * read
# access to *
# by self write
# by users read
# by anonymous auth
#
# if no access controls are present, the default policy
# allows anyone and everyone to read anything but restricts
# updates to rootdn. (e.g., "access to * by * read")
#
# rootdn can always read and write EVERYTHING!

For information, I also converted this configuration into cn=config with the
same result.
some commands after installation:
mkdir /usr/local/openldap/var/openldap-data
chown -R ldap:ldap /usr/local/openldap
Launch command:
/usr/local/openldap/libexec/slapd -h 'ldap://*:389 ldaps://*:636' -f
/usr/local/openldap/etc/openldap/slapd.conf -u ldap -g ldap -d -1
Establish connection with any client with manager credential on 389 port.
