LeakSanitizer/Valgrind errors in Binary_string::real_alloc upon INSERT DELAYED with unique blob and binary log

    XMLWordPrintable

    Details

      Description

      Note: I assume 10.4 is also affected, but currently the test case crashes on 10.4 with MDEV-22525 instead (in 10.5+ it was fixed within MDEV-19848).
      Note: The patch for MDEV-24467 is already in the branch.

      CREATE TABLE t (a TIMESTAMP, b TEXT, UNIQUE(a,b)) ENGINE=MyISAM;
      INSERT DELAYED INTO t VALUES ('2012-12-12','foo');
       
      # Cleanup
      DROP TABLE t;
