slapd daemon crashes complitely in such a situation:

I create my own class in shema

objectclass ( Tasks:Chain:Element
    NAME ('x-tch-e' 'x-Task-Chain-Element')
    MUST ( cn )
    MAY ( x-tch-nxt $ x-tch-sp $ x-tch-ep )
    DESC 'Container of pointers, next and previos'
    )

and an attribute wich should have multiple values

attributetype ( Tasks:Attr:3
    NAME ('x-tch-nxt' 'x-Task-Chain-Next')
    EQUALITY distinguishedNameMatch
    DESC 'Point to next chain element'
    SYNTAX distinguishedName
    )

Slapd starts sussesfully. It is possible add first x-tch-nxt attribute to an
entry, but if i try to add next one (usind ldapbrowser, or ldap_mod_add php
function) slapd stops (i have no such process any more)

this is what syslog say:
