Explain Analyse never returns .. maybe a bug

Hi all,

  I stop the following statement after 3 minutes....

   explain analyse select *
        From IC
        where IC.ICNUM NOT IN (select IRICNUM from IR WHERE IRSTATUT in
(1, 2))


I'm using 8.0.3 on windows.

Is that a know bug ?

Thanks
/David

P.S.: I can send more info if needed.
