Description of problem:
RHDS is crashing when using the nsRole filter rewriter with a filtered role that has an invalid filter.

Version-Release number of selected component (if applicable):
$ cat /etc/redhat-release
Red Hat Enterprise Linux release 9.4 (Plow)

$ rpm -qa | grep 389-ds

$

How reproducible:
Always.

Steps to Reproduce:
1. Create a filtered role with an invalid filter ( note the extra parenthesis right after the AND operator ):
$ ldapmodify -x -D "cn=Directory Manager" -W -H ldaps://localhost:7636 -a
Enter LDAP Password:
dn: cn=TestFilteredRole,ou=people,dc=example,dc=com
objectclass: top
objectclass: LDAPsubentry
objectclass: nsRoleDefinition
objectclass: nsComplexRoleDefinition
objectclass: nsFilteredRoleDefinition
cn: TestFilteredRole
nsRoleFilter: (&((objectClass=top)(objectClass=nsPerson))
Description: Test crash issue

adding new entry "cn=TestFilteredRole,ou=people,dc=example,dc=com"

$

2. Add the nsRole filter rewriter:
$ ldapmodify -x -D "cn=Directory Manager" -W -H ldaps://localhost:7636 -a
Enter LDAP Password:
dn: cn=roles,cn=rewriters,cn=config
objectClass: top
objectClass: extensibleObject
cn: roles
nsslapd-libPath: libroles-plugin
nsslapd-filterrewriter: role_nsRole_filter_rewriter

adding new entry "cn=roles,cn=rewriters,cn=config"

$

3. Restart the instance:
$ dsctl <INSTANCE> restart

4. A search using the filtered role will trigger the crash:
$ ldapsearch -xLLL -D "cn=Directory Manager" -W -H ldaps://localhost:7636 -b "dc=example,dc=com" "nsRole=cn=TestFilteredRole,ou=people,dc=example,dc=com"
Enter LDAP Password:
ldap_result: Can't contact LDAP server (-1)
$

5. No crash when using a valid filter:
$ ldapmodify -x -D "cn=Directory Manager" -W -H ldaps://localhost:7636
Enter LDAP Password:
dn: cn=TestFilteredRole,ou=people,dc=example,dc=com
changetype: modify
replace: nsRoleFilter
nsRoleFilter: (&(objectClass=top)(objectClass=nsPerson))

modifying entry "cn=TestFilteredRole,ou=people,dc=example,dc=com"

$

$ ldapsearch -xLLL -D "cn=Directory Manager" -W -H ldaps://localhost:7636 -b "dc=example,dc=com" "nsRole=cn=TestFilteredRole,ou=people,dc=example,dc=com" 1.1
Enter LDAP Password:
dn: uid=demo_user,ou=people,dc=example,dc=com

$

Actual results:
RHDS is crashing.

Expected results:
No crash.

Additional info:
I can reproduce with RHDS 11.8 ( RHEL 8.9 ) too.
