False positive for W534

[Thorsten_Schroff]

Hello,

in our project I get a false positive W534 (Class instance ''Foo'' passed to ''Bar'' but interface expected) warning.
I constructed a minimal example that reproduces the behaviour (I marked the line of question with a comment):

unit TFI.W534;

interface

uses
  System.Classes;

type
  IMyItem = interface(IInterface)
    ['{EAD54B97-1213-4076-B3A5-0A2D79F3962B}']
    function GetName: string;
    procedure SetName(const AName: string);

    property Name: String read GetName write SetName;
  end;

  TMyItem = class(TObject)
  strict private
    FName: string;
  public
    constructor Create(const AItem: IMyItem);
    property Name: string read FName write FName;
  end;

  TMyList = class(TList)
  public
    procedure Add(const AItem: IMyItem); reintroduce;
  end;

implementation

uses
  System.SysUtils;

var
  MList: TMyList;

{ TMyList }

procedure TMyList.Add(const AItem: IMyItem);
var
  LItem: TMyItem;
begin
  LItem := TMyItem.Create(AItem);
  inherited Add(LItem);    // This line issues a false positive W534, although inherited TList.Add expects a pointer, not an interface. It seems FixInsight doesn't get the "inherited" or the "reintroduce" right.
end;

{ TMyItem }

constructor TMyItem.Create(const AItem: IMyItem);
begin
  FName := AItem.Name;
end;

initialization

MList := TMyList.Create;

finalization

FreeAndNil(MList);

end.

Please let me known if you need further information on this. Thank you.

Kind regards,
Thorsten Schroff
