When limitation to use temporary tables in views is removed, please
add a test that shows what happens under LOCK TABLES when a view
references a temporary table, is locked, and the underlying table
is dropped.
create view v_bug5719 as select * from t2;
ERROR HY000: View's SELECT refers to a temporary table 't2'
Cleanup.
