Wrong results in COUNT() query with EXISTS and exists_to_in

Details

    • 10.2.10, 5.5.58, 10.1.29, 10.1.30, 10.2.12, 5.5.59

    Description

      A COUNT() query containing EXISTS and subqueries returns wrong results.
      Sometimes disabling the optimizer switch exists_to_in works as expected, I can't always reproduce this behaviour thou.
      Dropping an index (see sample.txt) also seems to fix, but there it's still 1 row off: 468 vs 469)
