Details

    • 10.1.31

    Description

      Lits of tests failing: main.multi_update main.mysql_client_test main.mysql_client_test_nonblock main.derived_view main.ps_ddl main.subselect_sj main.subselect_sj_jcl6 main.view. In normal, not in --ps-protocol.

      In all cases, the freed memory is read or written into in

          #0 0x603f51 in THD::rollback_item_tree_changes() sql/sql_class.cc:2257

      usually called from

          #1 0x6d3951 in Prepared_statement::cleanup_stmt() sql/sql_prepare.cc:3235
      		 
          #2 0x6e0a45 in Prepared_statement::execute(String*, bool) sql/sql_prepare.cc:3958
      		 
          #3 0x6e13e8 in Prepared_statement::execute_loop(String*, bool, unsigned char*, unsigned char*) sql/sql_prepare.cc:3591
      		 
          #4 0x6e1e9d in mysql_sql_stmt_execute(THD*) sql/sql_prepare.cc:2740

      At least in multi_update, it fails on the second execution of PS.
