OpenLDAP 2.4.23 (20100719)
UnixODBC 2.3.0
PostgreSQL 8.2.10

slapd starts fine, but when I make any search this is what I'm getting:
    
<= send_search_entry: conn 1000 exit.
send_ldap_result: conn=1000 op=2 p=3
send_ldap_result: err=0 matched="" text=""

in the syslog this is what I have:

and the gdb backtrace shows this:

Everything works fine in 32bits (Debian 5.0 i386), but it fails with 64bits.

Any idea?
