Минимальный пример:

using namespace System;

//#using <System.Core.dll>

class A
{
public:
    const wchar_t* F() { return L""; }
};

String^ readUnicodeString(A& msg)
{
    const wchar_t* text = msg.F();
    String^ str = gcnew String(text); // <<< ICE указывает сюда
    return str;
}

int main() {}

Если раскомментировать то получаем ICE.

Со старым синтаксисом управляемого C++ всё компилируется без проблем.
Есть идеи как обойти ?
