slapd: Illegal Instruction on solaris 9

[Greg Matthews <gmatt@nerc.ac.uk>]

when starting slapd with the -u flag:

budbase openldap-data # /usr/local/libexec/slapd -u ldap -d1
@(#) $OpenLDAP: slapd 2.1.25 (Feb 10 2004 13:43:20) $
        susa@mtdbase:/scratch/openldap-2.1.25/servers/slapd
daemon_init: listen on ldap:///
daemon_init: 1 listeners to open...
ldap_url_parse_ext(ldap:///)
daemon: initialized ldap:///
daemon_init: 2 listeners opened
ldap_create
ldap_unbind
ldap_create
ldap_create
Illegal Instruction

starting as root works as expected:

budbase / # /usr/local/libexec/slapd -d1
@(#) $OpenLDAP: slapd 2.1.25 (Feb 10 2004 13:43:20) $
        susa@mtdbase:/scratch/openldap-2.1.25/servers/slapd
daemon_init: listen on ldap:///
daemon_init: 1 listeners to open...
ldap_url_parse_ext(ldap:///)
daemon: initialized ldap:///
daemon_init: 2 listeners opened
slapd init: initiated server.
bdb_initialize: initialize BDB backend
...

what are the ldap_create and ldap_unbind bits? what is slapd trying to
do at this point? I've triple checked permissions in
/usr/local/etc/openldap and also the data directory. I've removed the
directory data and tried starting without data. I've replaced with known
good binaries all with the same result. If I can know what slapd is
trying to do at this point then I can hopefully find the problem on the
box.

here is a backtrace but I dont know enough to understand it:
