Delphi code migration issues

I´m facing a problem between Delphi 2010 and Delphi Berlin (last update) during my code migration.... I made a simple code to demonstrante an strange behaviour...

I have an application that use TList (the former one) and TList (from Generics.Collections) I know that this piece of code (below) doesn´t make any sense for you, but it´s for demonstration purposes

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.

At Delphi 2010 the ShowMessage shows 'A' character, but on the Delphi Berlin it raises an Acess Violation

Both applications with Optimization set to False
