In FPC 3.3.1, accessing private field (in generic) from the specialization is not allowed anymore

{$mode objfpc}{$H+}{$J-}

unit MyGenericClass;

interface

type
  generic TMyGenericClass<T> = class
  private
    PrivateInClass: T;
  public
    PublicInClass: T;
  end;

implementation

end.

uses MyGenericClass;

type
  TMyClass = class(specialize TMyGenericClass<Integer>)
    procedure MyMethod;
  end;

procedure TMyClass.MyMethod;
begin
  PrivateInClass := 123; // works in FPC 3.2.2, doesn't in FPC 3.3.1 (and FPC 3.3.1 is better IMHO!)
  PublicInClass := 123;
end;

begin
end.
