Assertion `marked_for_read()' failed in Field_long::val_str (and other types) on nested SELECT, ASAN heap-use-after-free in Item_field::print

Details

    Description

      There quite a few marked_for_read bugs, but none looks related or identical, and this one requires the optimizer_trace option to be set. This bug does not seem to be a regression as optimizer_trace is not available in 10.3.

      SET SESSION optimizer_trace="enabled=on";
      		 
      CREATE TABLE t1 (i INT) ENGINE=InnoDB;
      		 
      CREATE TABLE t2 (c INT) ENGINE=MyISAM;
      		 
      INSERT INTO t2 VALUES (1);
      		 
      SELECT 1 FROM (SELECT 1 IN (SELECT 1 FROM t1 WHERE (SELECT 1 FROM t2 HAVING c)) FROM t2) AS z;

      Leads to:
