BUG when migrating from 8.0 to 8.1 with create temp table

Hi all,

  I just migrated from 8.0 to 8.1 and one of my stored procecure just
hang when trying to create a temp table

Here is my call:

select * from usp_Comptabilite_AgeDeCompteClient('M', null,
'2005-01-28', '1', '1', '0', null)

If you look below in the log you will see that the function just hang
when creating T_CP1 table.

Is that a know bug .. this code worked with 8.0

Thanks for your help
Best Regards
/David
