We are experiencing some problems with a certain searchstring on openldap 2.0.18
and 19.
Slapd aborts with: schema_init.c:1311: caseIgnoreSubstringsMatch: Assertion `idx
< left.bv_len' failed.
(With openldap 2.0.11 the same searchstring created an abort
with:schema_init.c:3221: numericStringNormalize: Assertion `newval->bv_val < p'
failed. NOTE:I tried a numeric definition of the attribute here, so don't get
confused)

We are running openldap on a redhat 7.1 system with some attributes we've
created ourselves.
The attribute on which we get the error is defined as:
attributetype ( 5.5.5.5.8
        NAME 'ozsBirthday'
        DESC 'OZS Geboortedatum'
        EQUALITY caseIgnoreMatch
        SUBSTR caseIgnoreSubstringsMatch
        SYNTAX 1.3.6.1.4.1.1466.115.121.1.26)

With the following search slapd stops:
ldapsearch -v -x -w geheim -D "cn=manager,o=ozs,c=nl" -b "o=ozs,c=nl" -h
127.0.0.1 "(ozsBirthday=*01*30)"

Slapd output:
