Hi,
Consider:
-- p.ads
with Ada.Finalization;
package P is
type T is new Ada.Finalization.Controlled with null record;
end P;
Just specification. Let's compile it:
$ gnatmake -gnatv -gnatwd -c p
gnatgcc -c -gnatv -gnatwd p.ads
GNAT GPL 2005 (20050729)
Copyright 1992-2005 Free Software Foundation, Inc.
Compiling: p.ads (source file time stamp: 2007-01-20 20:09:07)
3. type T is new Ada.Finalization.Controlled with null record;
|
>>> warning: implicit dereference
4 lines: No errors, 1 warning
What's more funny, there is no problem with Limited_Controlled.
Am I just unlucky while trying to learn Ada? :-)

I don't get this with GNAT 4.1.2 or with GNAT Pro 5.05w.
Ciao,
