Hi,

Is this a GNAT (GPL-2015) bug or my not understanding Ada?

I was surprised that I could compile
  procedure Test (V : out Positive) is null;

and even more by the results of calling the procedure 

  V : Positive;
begin
  Test (V);
  Ada.Text_IO.Put_Line ("V:" & V'img);

The value zero is output, which because V is positive should be impossible.

I would have thought that null procedures with out parameters would fail to compile. 

Opinions anyone?

MfG
