(ITS#6452) Able to crash slapd when using identity assertion

Full_Name: J Version: 2.4.20 OS: Debian-Lenny/amd64 URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (68.15.14.98)

Able to do all necessary identity assertion when using command-line tools (ldapsearch, ldapmodify, etc) against my server. Server is running back_ldap, back_relay, pcache and back_hdb.

But when I point one of my test hosts (Debian Lenny) against this seemingly healthy server and I try to login, I get this while running slapd -d -1:

[rw] searchEntryDN: "uid=jay,cn=plain,cn=auth,dc=example,dc=com" -> "uid=jay,cn=plain,cn=auth,dc=example,dc=com" slapd: /usr/src/openldap-src-2.4.20/openldap-2.4.20/servers/slapd/entry.c:483: entry_clean: Assertion `e->e_private == ((void *)0)' failed. Aborted

Why?
