>Description:
        When firing up current OpenLDAP with bdb backend (the old but
        working ldbm backend was removed), OpenLDAP crashes horribly after
        importing some data whenever a search is requested.

        gdb says:

Program received signal SIGSEGV, Segmentation fault.

        # pgrep slapd && echo alright
        alright
