       {
         "query_block": {
      -    "select_id": 1,
      -    "r_loops": 1,
      +    "select_id": -1637998592,
      +    "r_loops": -1637998592,
           "r_total_time_ms": "REPLACED",
           "table": {
             "table_name": "t3",
             "access_type": "ALL",
      -      "r_loops": 1,
      -      "rows": 10,
      +      "r_loops": -1637998592,
      +      "rows": -1637998592,
             "r_rows": 10,
             "r_total_time_ms": "REPLACED",
             "filtered": 100,
      

      The failures are intermittent, suggesting reading of uninitialised data.
