    Description

      CREATE TABLE t (t INT);
      		 
      INSERT INTO t VALUES (0),(t IN (SELECT t IN (SELECT 1 FROM (SELECT 1 AS t) AS t WHERE t IN (SELECT t HAVING NOT t))));

      This testcase only crashes 10.5 to 10.11, debug, with UniqueID/stack:

      (engine->uncacheable() & ~8) || ! engine->is_executed() || with_recursive_reference|SIGABRT|Item_in_subselect::val_bool|Item::val_bool_result|Item_in_optimizer::val_int|Type_handler_int_result::Item_val_bool
