Hello,

I've built openldap 2.4.45 on a CentOS 7.4.1708 machine with the following configuration:

./configure --enable-bdb=no --enable-hdb=no --enable-mdb --with-tls=openssl --enable-spasswd --enable-syslog --enable-modules --enable-cleartext --enable-overlays --enable-accesslog --enable-auditlog --with-threads --enable-shared --enable-ldap --enable-monitor --enable-deref --enable-slapd --enable-ppolicy --enable-memberof

When I run make test I receive numerous segmentation faults:

output from make test:

./scripts/test028-idassert: line 252: 28923 Segmentation fault (core dumped) $SLAPD -f $CONF1 -h $URI1 -d $LVL $TIMING > $LOG1 2>&1

...

test028-idassert completed OK for mdb.
