Per Marko and Thiru:

The problems are most probably caused by MDEV-16329.

Scenario:

1. Start the server and generate some initial data.

2. Several session run concurrent some DDL/DML mix

    Sometimes this kind of test fails with

     ALTER TABLE t3 MODIFY COLUMN col2 INT NOT NULL, LOCK = DEFAULT  /* E_R Thread2 QNO 2894 CON_ID 15 */  failed: 1032 , errstr: Can't find record in 't3'

     pluto:/data/results/1693844534/TBR-403--TBR-403D_1$ _RR_TRACE_DIR=./1/rr/ rr replay --mark-stdio

    or

    ALTER TABLE t1 DROP PRIMARY KEY, ALGORITHM = DEFAULT, LOCK = DEFAULT  /* E_R Thread16 QNO 59 CON_ID 28 */  failed: 1032 , errstr: Can't find record in 't1'

    pluto:/data/results/1693844534/TBR-403--TBR-403F--TBR-403D_better$ _RR_TRACE_DIR=./1/rr/ rr replay --mark-stdio
