**How to reproduce**
```
SELECT number, nth_value(number, '10') OVER w AS secondValue, nth_value(number, 2147483647) OVER w AS thirdValue FROM numbers(1.) WINDOW w AS (ORDER BY number ASC) ORDER BY toInt64(2147483646 - intDiv(number, 2147483647), toInt64(number, NULL - intDiv(number, NULL), 100000002004087730000.)) ASC, number DESC NULLS FIRST
```

```
Changed settings: max_block_size = '1', max_threads = '1', receive_timeout = '10', receive_data_timeout_ms = '10000', max_rows_to_read = '3', engine_file_empty_if_not_exists = '0'
```
offset = x.row - block_rows;
                x.row = 0;
                x.block++;
                if (x == blocksEnd())
                {
                    break;
                }
            }
            else
            {
                offset = 0;
                break;
            }
        }
    }
    else if (offset < 0)

            assert(offset <= 0);
            
            
            assert(offset >= -INT64_MAX);
            if (x.row >= static_cast<uint64_t>(-offset))
            {
                x.row -= -offset;
