Compiler bug when using generics and forward declaration in Delphi XE2

I started project on Delphi 2010, then migrated to XE and now I try to migrate to XE2. After compiling in XE2 (Update 4 Hotfix 1), unit tests began fail with AV. After some debugging, it became clear that the following code is not correctly compiled:

program ForwardDeclaration;

{$APPTYPE CONSOLE}

uses
    System.SysUtils;

type
    TEntityBase = class(TObject)
    protected
        FModel: Integer;
    public
        constructor Create(const AModel: Integer);
    end;

    TEntity<TKey> = class(TEntityBase)
    end;

    TMyEntity2 = class;

    TMyEntity1 = class(TEntity<Integer>)
        FData: Integer;
    end;

    TMyEntity2 = class(TMyEntity1)
    end;

constructor TEntityBase.Create(const AModel: Integer);
begin
    inherited Create;
    FModel := AModel;
end;

var
    MyEntity: TMyEntity1;
begin
    try
        Writeln(TEntityBase.ClassName, ': ', TEntityBase.InstanceSize, ' bytes');
        Writeln(TMyEntity1.ClassName, ': ', TMyEntity1.InstanceSize, ' bytes');
        MyEntity := TMyEntity1.Create(100);
        Assert(MyEntity.FData = 0);
    except
        on E: Exception do Writeln(E.ClassName, ': ', E.Message);
    end;
end.

Program outputs:

TEntityBase: 12 bytes
TMyEntity1: 12 bytes <-- Must be 16 bytes!
EAssertionFailed: Assertion failure (ForwardDeclaration.dpr, line 41)

Is it possible to resolve the problem by tuning compiler options?

Whether this problem repeats at someone else?
