Hi everyone,
I have the following simple test application:
package Full_View is
type Base_Type (Num : Integer) is tagged private;
type Base_Interface is interface;
type New_Type is new Base_Type (Num => 11) and
Base_Interface with private;
private
type Base_Type (Num : Integer) is tagged record
My_Number : Integer := Num;
end record;
type New_Type is new Base_Type (Num => 11) and
Base_Interface with null record;
end Full_View;
Trying to compile this with gnat gcc 4.3 in Debian/Lenny results in the
following error:
full_view.ads:7:09: interface "Base_Interface" not implemented by full
type (RM-2005 7.3 (7.3/2))
When removing the (Num => 11) discrimant initialization or the
Base_Interface interface from the New_Type type extension, the code
compiles fine.
Is this a compiler bug? Seems to me that the consistency check of the
partial and full view of a tagged type covering interfaces does not like
discriminants.
Thanks for your help.
