I could get slaptest/slapd to produce a segmentation fault by using the unique
overlay and a unique_uri with a base dn. This behaviour depends on the position
of the overlay/unique_uri in slapd.conf and doesn't appear if you don't use a
base dn regardless of the position. (I know an overlay should be defined after
the other configuration settings have been set. I encountered this bug when I
put it in the first part by mistake, see below) 

I could reproduce this with OpenLdap 2.4.9 from Ubuntu 8.04.1 server as well as
a fresh compiled OpenLdap 2.4.11 on Ubuntu 8.04.1 and Centos 4.6

How to reproduce:

Take a (very simple) OpenLdap installation and put the overlay stuff before the
suffix configuration:

-------------------------------------------------------------
.
.
moduleload      unique
.
.
#######################################################################
# Specific Directives for database #1, of type hdb:
# Database specific directives apply to this databasse until another
# 'database' directive occurs
database        hdb

# The base of your directory in database #1

overlay         unique
unique_uri      ldap:///"dc=my-domain,dc=com"?gidNumber?sub

suffix          "dc=my-domain,dc=com"

.
.
-------------------------------------------------------

Then check the configuration:

ldapmaster-dev:/etc/ldap#slaptest
Segmentation fault

ldapmaster-dev:/etc/ldap#slapd -d 4
Segmentation fault

Putting the overlay stuff at the end of the database section or the suffix
configuration before the overly stuff it works as expected. It also works
without a base dn  (unique_uri  ldap:///?gidNumber?sub) regardless of the
position.
