            With credit to Elena who found a great shorter testcase:

            SET @cmd:="SET @x=(SELECT 'a')";
            		 
            SET @@SESSION.OPTIMIZER_SWITCH="materialization=OFF,in_to_exists=OFF";
            		 
            PREPARE stmt FROM @cmd;

            This is a fairly common assert it seems, and may block other bugs from showing. I am currently seeing another crash in:

            !is_set() || (m_status == DA_OK_BULK && is_bulk_op())|SIGABRT|Diagnostics_area::set_ok_status|my_ok|mysql_load|mysql_execute_command

            Vs the one from this bug:

            !is_set() || (m_status == DA_OK_BULK && is_bulk_op())|SIGABRT|Diagnostics_area::set_ok_status|my_ok|mysql_sql_stmt_prepare|mysql_execute_command

            On a very different use case. A fix would be great to avoid filtering this generic assert and thereby masking other bugs.
