I have the following indexing configured in slapd.conf:

index cn pres,eq,sub,approx
index givenName pres,eq,sub,approx

When I use slapadd to add entries with UTF-8 characters in them, slapadd
segfaults. Here is an example LDIF file:

dn: o=test.com
objectclass: top
objectclass: organization
o: test.com

dn: uid=juergen_test@test.com, o=test.com
objectclass: top
objectclass: person
objectclass: organizationalPerson
objectclass: inetOrgPerson
cn:: SsO8cmdlbiBUZXN0
sn: Test
givenname:: SsO8cmdlbg==
uid: juergen_test@test.com 

Here's a backtrace from gdb when running slapadd on this file, at the point of
failure:
