Test case:

create or alter view v_test (id, col)
as
select rdb$relation_id, 1 from rdb$relations;

commit;

-- reconnect;

create or alter view v_test (id)
as
select rdb$relation_id from rdb$relations
union all
select rdb$relation_id from rdb$relations;

commit; -- here the crash happens

This is a regression introduced while fixing CORE2386.
