Delphi代码迁移问题

我有一个使用TList(前一个)和TList(来自Generics.Collections)的应用程序
我知道这段代码(下面)对你没有任何意义,但它是出于演示目的

unit Unit1;
interface
uses
  Winapi.Windows,Winapi.Messages,System.SysUtils,System.Variants,System.Classes,Vcl.Graphics,Vcl.Controls,Vcl.Forms,Vcl.Dialogs,Vcl.StdCtrls;
type
  TTest = class
    Name: string;
    constructor Create(Nome: string);
  end;
  TForm1 = class(TForm)
    btn1: TButton;
    procedure btn1Click(Sender: TObject);
    procedure FormCreate(Sender: TObject);
  private
    FList: TList;
  end;
var
  Form1: TForm1;
implementation
uses
  System.Generics.Collections;
{$R *.dfm}

procedure TForm1.btn1Click(Sender: TObject);
var
  tmpList: TList<TTest>;
begin
  tmpList := TList<TTest>.Create;
  tmpList.Add(TTest.Create('A'));
  tmpList.Add(TTest.Create('B'));
  tmpList.Add(TTest.Create('C'));
  tmpList.Add(TTest.Create('D'));
  tmpList.Add(TTest.Create('E'));
  FList := TList(tmpList);
  ShowMessage(TTest(FList[0]).Name);
end;

procedure TForm1.FormCreate(Sender: TObject);
begin
  FList := TList.Create;
end;

constructor TTest.Create(Nome: string);
begin
  Name := Nome;
end;
end.

在Delphi 2010中,ShowMessage显示’A’字符,但在Delphi Berlin上它引发了Acess违规

优化的两个应用程序都设置为False
