this is not a crash it's smb_panic() in action:-)
and status == NT_STATUS_UNSUCCESSFUL == NT_STATUS(0xC0000000 | 0x0001)
== 3221225473

        } else {
                TDB_DATA data;
                NTSTATUS status;

                data.dsize = br_lck->num_locks * sizeof(struct lock_struct);

                status = br_lck->record->store(br_lck->record, data,
                                               TDB_REPLACE);

entry\n");
