Test case:

create table A (ID int);
create table B (ID int);
create index IDX on A computed by (ID);

select min( (select 1 from A where cast(ID as int) = http://B.ID) ) from B
-- ERROR: bad BLR -- invalid stream.

This error is not present if computed index is not created or if CAST is omitted inside the query.

After this fix does not work this:

recreate table G ( ID Integer, OBJECT_ID computed by (ID) );
commit;
insert into G( OBJECT_ID ) values( 1 );

with message

This column cannot be updated because it is derived from an SQL function or expression.
attempted update of read-only column.

It's the result of CORE3874, not this one.
