Re: Yet another gnat bug

[Per Sandberg <per.s.sandberg@bahnhof.se>]

I did put some effort to reduce the problem and the workaround is quite 
simple, in file "wann-nets.ads:69" mark the procedure Del_Neuron as 
abstract instead of null.

Here is the small reproducible i ended up with after stripping the code:
-----------------------------------------------------------------
pragma Warnings (Off);
generic
     type Real is digits <>;
package wann is
end Wann;
--
generic
package Wann.Neurons is
end Wann.Neurons;
---
generic
package Wann.Nets is
    type NNet_Interface is limited interface;
    procedure Del (Net : in out NNet_Interface) is null;--  Fails
    --procedure Del (Net : in out NNet_Interface) is abstract;--  Works
    type Cached_NNet_Interface is limited interface and NNet_Interface
end Wann.Nets;
--
generic
package wann.nets.vectors is
     type Proto_NNet is abstract new NNet_Interface with NULL record;
     type Cached_Proto_NNet is abstract new Proto_NNet and 
Cached_NNet_Interface with null record;
end wann.nets.vectors;
--
pragma Warnings (Off);
with wann.nets.vectors;
procedure run_customNN is
     package PW is new wann(Real => Float);
     package PNet   is new PW.nets;
     package PNetV  is new PNet.vectors;
begin
    null;
end Run_CustomNN;
