seg fault during slapindex

[tpublic@metro-email.com]

Hello,
I'm looking for help with an index building problem. I am running Apple 
(Tiger) Open Directory which uses slapd 2.2.19. Upgrading is 
unfortunately not an option because the OS has tools / GUI built around 
the database. I had noticed some errors in our slapd.log indicating  we 
needed additional indexes built:


 bdb_equality_candidates: (kerio-Mail-AccountEnabled) index_param 
failed (18)\n
 bdb_equality_candidates: (kerio-Mail-Address) index_param failed (18)\n
 bdb_substring_candidates: (apple-group-realname) index_param failed (18)\n
 bdb_substring_candidates: (givenName) index_param failed (18)\n
 bdb_substring_candidates: (mail) index_param failed (18)\n


So I attempted to create the missing indexes, but slapindex crashes with 
a segmentation fault unless I disable most of my config changes. The 
lines commented out are the ones which caused a fault:

slapd.conf:

 include /etc/openldap/slapd_macosxserver.conf
 #index  kerio-Mail-Address eq # Seg faults.
 index  kerio-Mail-AccountEnabled eq


slapd_macosxserver.conf (included via slapd.conf):

 # Adding ",sub" to apple-group-realname, due to errors in 
/var/log/slapd.log
 #index   apple-group-realname   eq
 index   apple-group-realname    eq,sub
 [...]
 # Adding mail & givenName indices, due to errors in /var/log/slapd.log
 # Both of these cause seg fault on slapindex
 #index   mail           sub
 #index   givenName      sub


I verified that the index names I configured match exactly the spelling 
in the error messages. Also slaptest ran successfully. I ran db_recover 
to no avail (slapindex was initially hanging even if I just used my base 
configuration).

Any hints would be greatly appreciated. I realize this is an older 
version, but hopefully there are some tricks that I could use to work 
around it? If not, could I install the current openldap, in a different 
location, build the indexes, and copy them over?
