-----------------------------------------------------

                 Key: CORE-4146
                 URL: http://tracker.firebirdsql.org/browse/CORE-4146
             Project: Firebird Core
          Issue Type: Bug

            Reporter: Nick Dirov


select distinct f1, list(f2)
from
    (select f1, f2
       from
        (select 1 as f1, 'a' as f2 from rdb$database
        union
        select 2 as f1, 'b' as f2  from rdb$database
        union
        select 2 as f1, 'c' as f2  from rdb$database
        union
        select 3 as f1, 'e' as f2  from rdb$database)
    order by 1, 2 desc)
group by 1

return
1- a
2- b,c 
3- e

instead of expected
1- a
2- c,b
    ^^^^ 
3- e

so as we watch order by clause ignored when group by distinct ..
