Bugreport: openldap 2.4.48-1 ldapsearch coredump

[Alexander Voropay]

Hi!

Ildapsearch coredumps on (semi) complicated filter on MS AD LDAP
(Filtered request to find all non-blocked users w/o e-mail address).

(I've changed our domain name and output, sorry, DN is in UNICODE)
===
$ ldapsearch -H ldaps://SPSDCMAIN.office.local -x -W -D
"User.NM@office.local" -b "dc=office,dc=local"
'(&(objectClass=user)(objectCategory=user)(postOfficeBox=*)(!(userAccountControl:1.2.840.113556.1.4.803:=2))(!(mail=*)))'
sAMAccountName
Enter LDAP Password:
# extended LDIF
#
# LDAPv3
# base <dc=office,dc=local> with scope subtree
# filter:
(&(objectClass=user)(objectCategory=user)(postOfficeBox=*)(!(userAccountControl:1.2.840.113556.1.4.803:=2))(!(mail=*)))
# requesting: sAMAccountName
#

# \D0\A1\D0\BC\D1\83\xxxxxxxxxxxxx\87, Rezerved, ServicesAccount
 s, Users, SPB, office.local
dn:: Q0490KHQvNGxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
Segmentation fault (core dumped)

The _same_ request works on the RHEL 7 ldapsearch "openldap-2.4.44-21.el7_6"

Does it work on RHEL7 with OpenLDAP 2.4.48?

You can get RHEL7 packages from <https://repo.symas.com/sofl/rhel7/> or 
<https://ltb-project.org/documentation/openldap-rpm#yum_repository>

As noted in the announcement, that's what I am seeing in the testsuite
as well, I have not yet figured out what exactly goes wrong.
