Hi!
Can you help me?
I'm stuck with following example.

I expected statement
  return Statement'(Ada.Finalization.Controlled with C => 0);
created object of type Statement,
then Initialyze procedure would be called for it and
Put_Line printed "Init".

But when I compile program with GNAT 3.15p for Linux
it doesn't happen.

May be it's bug of GNAT?

Thank you

Maxim Reznik
