Description of problem:
When I configure postfix to use a LDAP directory to lookup information
(relay_recipient_maps in this case) it doesn't work. Postfix makes a connection
to the openldap server, the query is performed and a segmentation fault occurs
when there is a matching object in LDAP. When there is no matching object from
LDAP, the postmap command finishes without a segmentation fault.

When I copy the configuration file to a i386 machine (also with FC5) there's no
segmentation fault and it returns the data from the LDAP directory.

Thanks in advance for looking into this problem. Please let me know if more
information is needed. or if I can do anything to help solve this issue. 

Version-Release number of selected component (if applicable):
postfix-2.2.8-1.2
openldap-servers-2.3.19-4


How reproducible:
Always, when there is object in LDAP matching the search filter 

Steps to Reproduce:
1. Configure postfix for ldap lookups on i386
2. Test with postmap (postmap -q 'test'
ldap:/etc/postfix/relay_recipient_maps_ldap.cf
3. Bang! :)
  
Actual results:
[root@x86_64 postfix]# postmap -q 'test'
ldap:./relay_recipient_maps_ldap.cf
Segmentation fault
[root@x86_64 postfix]#

Expected results:
[root@i386 postfix]# postmap -q 'test'
ldap:./relay_recipient_maps_ldap.cf
test
[root@i386 postfix]#


Additional info:

Some gdb output (with postfix-debuginfo) is attached

Relevant part of main.cf:
relay_recipient_maps = ldap:/etc/postfix/relay_recipient_maps_ldap.cf 

relay_recipient_maps_ldap.cf:
server_host = ldap://ldap
search_base = dc=example,dc=com
query_filter = (mail=%s)
result_attribute = mail
bind = yes
bind_dn = cn=postfix,ou=services,dc=example,dc=com
bind_pw = password
