Re: Controlled Types & GNAT 3.09

[Jerome Desquilbet <jDesquilbet@Rational.COM>]

Alexander,

There's a bug in GNAT, but it is not where you think. The program you
propose should write:

Main Begin ----
F1 := F2
B1 := B2
Main End ----

And that's all! Why?

You declared:

> package Foo_Controlled  is
> 
>    type Foo is private;
>    procedure Initialize(F: in out Foo);
>    procedure Adjust(F: in out Foo);
>    procedure Finalize(F: in out Foo);
> 
> private

[...]

> end Foo_Controlled;

and same kind of declaration for Bar.
At the place you declare Initialize, Adjust and Finalize, you are in the
partial view of the type. You simply declare subprograms, that have
nothing to do with the inherited subprograms from Controlled, because at
the place you declare them, the type is not known as inheriting from
Controlled.

Put Initialize, Adjust and Finalize in the full view (i.e. at the end of
the private part in your example) and it will work.

Regards,

  Jerome.

PS: tested with Apex 2.2.2B.
