User(s) can reproduce this bug

When we add a reference to System.Core, we find an issue which related to managed class String^. If we turn off the Precompiled Headers, any use of String::Format() always causes the crash. Also in another class that did some string marshalling it causes a crash in the msclr\marshal.h file on line 49.

This problem can be reproduced using VS2008, VS2010 (Toolsets V90) with .Net Framework 3.5.

Visual Studio 2010

Performance

1.Create a new System Console CLR project in C++
2.Add a reference to System.Core
3.Set Create/Use Precompiled Header to "Not Using Precompiled Headers" -IMPORTANT
4.Add the following code and hit CTRL-F7 - The compiler crashes.
5.Comment out the Line that starts with String^
6.Hit CTRL-F7 the code compiles.

#include "stdafx.h"

using namespace System;
using namespace System::IO;
using namespace System::IO::Pipes;

int main(array<System::String ^> ^args)
{
NamedPipeServerStream^ pipe_stream = gcnew NamedPipeServerStream("test",PipeDirection::InOut);
String^ msg = String::Format("This will cause the compiler to crash {0} when System.Core is referenced",1);
Console::WriteLine(L"Hello World");
return 0;
}
