There is Bug in IDE on my mind

Start C++ Builder any application, change compiler to new one. If you want to change property of object for example form caption from lampda function, you get : 

ICE: Internal compiler error: C0000005 @ 539FCE99 in the first line of this file, and you "do not know why"

Steps to reproduce:

Change compiler to new one, add

#include "System.Threading.hpp"

and 

_di_ITask task = TTask::Create([&]() {
Caption = "I know, it's wrong but: WHY there is [bcc32c Error] Unit2.cpp(1): ICE: Internal compiler error: C0000005 @ 539FCE99 IN FIRST LINE OF THIS FILE"; });

to any function.
