Bug #32400: Complex SELECT query returns correct result

Browse Source 
only on some occasions

Referencing an element from the SELECT list in a WHERE 
clause is not permitted. The namespace of the WHERE
clause is the table columns only. This was not enforced
correctly when resolving outer references in sub-queries.

Fixed by not allowing references to aliases in a 
sub-query in WHERE.
