Bug Description

I am trying to use a couple of "unique" overlays, but when adding new entries in my database, I get a failed assertion in server:

slapd: search.c:970: oc_filter: Assertion `f != ((void *)0)' failed.

I think the problem occurs only when the first overlay does not detect violations, but the second does. I not tested the other case yet, but if I swap overlay declarations in "maindb-commonparams.conf", the crash also happens.

Running Ubuntu Hardy Heron, x86 architecture, OpenLDAP version is 2.4.9-0ubuntu0.8.04. But I did a step forward and saw the same bug in OpenLDAP 2.4.10 I compiled by myself.

Steps to reproduce:

# Download and extract the attached file in an existing folder "/home/amg1127".
# Change working directory to "/home/amg1127/ldap"
# Run "./create-master-base.sh"
# Run "./run-master-slapd.sh"
# In another terminal, run: "./crash-server.sh"
# slapd: search.c:970: oc_filter: Assertion `f != ((void *)0)' failed.

I used these flags while compiling OpenLDAP 2.4.10:

# ./configure --prefix=/home/amg1127/openldap-2.4.10-bin --enable-dynamic --enable-spasswd --enable-modules --enable-slapi --enable-backends=mod --enable-overlays=mod --with-tls=gnutls

I can reproduce the bug in OpenLDAP 2.4.10, so I will open an ITS and paste URL here in some minutes.

Thanks.
