Assertion `!is_set() || (m_status == DA_OK_BULK && is_bulk_op())' failed upon SELECT from S3 table with concurrent BACKUP stage

    Details

      Description

      Note: it fails for me every time, but it's still a concurrent and hence non-deterministic test case. Run with --repeat=N if it doesn't fail right away.

      CREATE TABLE t1 (a INT);
      ALTER TABLE t1 ENGINE=S3;
       
      --connect (con1,localhost,root,,test)
      BACKUP STAGE START;
       
      --connection default
      --send
      SELECT * FROM t1;
       
      --connection con1
      BACKUP STAGE BLOCK_COMMIT;
       
      # Cleanup
      BACKUP STAGE END;
      --disconnect con1
      --connection default
      --reap
      DROP TABLE t1;
