SIGSEGV in heap_info on second stored procedure call

    XMLWordPrintable

    Details

      Description

      Somewhat similar to MDEV-23213, but the versions affected are different and optimizer setting derived_merge is not modified/used here. Also noting that MDEV-23213 does not reproduce on MySQL 5.5 as derived_merge is not implemented there.

      CREATE TABLE t2 (c INT,c2 CHAR(1),c3 DATE) ENGINE=InnoDB;
      CREATE PROCEDURE p (cnt INT(1)) SELECT COUNT(*) INTO cnt FROM t;
      CREATE VIEW t AS SELECT * FROM t2;
      CREATE TEMPORARY TABLE t (c TEXT);
      CALL p (1);
      DROP TEMPORARY TABLE IF EXISTS t,t2;
      CALL p (1);
      

      Leads to:
