on a query like:

  SELECT a.col1, a.col5, a.col4, a.col2, a.col6  , a.col3,
a.col7,     0
       as I_ARBOL,  (Select count(b.col1     ) from table_a
as b where
      trim(b.col2)           = trim(a.col1))      as childs ,
a.col8  FROM
    table_a       as a  WHERE a.col1      = 04071400000000 and
a.col8      = 1
        and a.col7     = 'MC'  ORDER BY a.col1

If correct type is used in filter  i.e. '04071400000000' query
returns correct, but it should not crash engine if badly
constructed and should return -880.
