User(s) can reproduce this bug

I have a bug in Visual Studio 2008 (but users of VS2010 report problems also) that causes the optimizing compiler to crash. I asked users on the forum to try and reproduce the bug and got positive results. You can see the thread here.

My actual version was VS 2008 Team Edition SP1
My quest to solve this issue started on a separate thread which has even more details.

Reliability

Create a new System Console CLR project in C++
Add a reference to System.Core
Set Create/Use Precompiled Header to "Not Using Precompiled Headers" -IMPORTANT
Add the code shown below and hit CTRL-F7 - The compiler crashes at this point for me
Comment out the Line that starts with String^
Hit CTRL-F7 the code compiles.

NOTE: Step 3 is key to seeing this bug. You can modify the precompiled header setting from the Project->Properties menu. In the resulting dialog, select the Configuration Properties->C/C++->Precompiled Headers option in the left panel. Then the first option on the right can be changed with a drop down choice.

#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;
}

Expected a clean compile.

I installed the hotfix to KB976656 (which is not intended to fix C1001) and compilation worked.
