> message:
>   Bug #48293: crash with procedure analyse, view with > 10 columns,
>   having clause...
>   
>   The fix for bug 46184 was not very complete. It was not covering
>   views using temporary tables and multiple tables in a FROM clause.
>   Fixed by reverting the fix for 46184 and making a more general
>   check that is checking at the right execution stage and for all
>   of the non-supported cases.
>   Now PROCEDURE ANALYZE on non-top level SELECT is also forbidden.
>   Updated the analyse.test and subselect.test accordingly.
