AutoCAD 2005 & VS2005 C++/CLR: fatal error C1001

I'm testing AutoCAD 2005 automation via VS2005 Pro C++/CLR and I'm getting
fatal compiler errors.

I start with a default C++/CLR class library project and modify it by adding
the following references:

acdbmgd.dll
acmgd.dll

the entire source for the default library header file is:

// DotNetBug.h

#pragma once

using namespace System;

typedef Autodesk::AutoCAD::ApplicationServices::CommandLinePrompts CmdLine;
typedef Autodesk::AutoCAD::DatabaseServices::Handle Handle;
typedef Autodesk::AutoCAD::DatabaseServices::DBObject DBObject;
typedef Autodesk::AutoCAD::Runtime::RXClass RXClass;

namespace DotNetBug
{

public ref class Class1 : public
Autodesk::AutoCAD::Runtime::IExtensionApplication
{
public:

virtual void Initialize()
{
CmdLine::Message( System::Convert::ToString( "\nAutoCAD
extensions loaded!\n" ) );
}

virtual void Terminate()
{
CmdLine::Message( System::Convert::ToString( "\nAutoCAD
extensions unloaded!\n" ) );
}
};

public ref class Commands
{
public:

[Autodesk::AutoCAD::Runtime::CommandMethod("hello")]
static void Hello()
{
CmdLine::Message( "\nHello from C++!\n" );

//===============================================
// It seems that any use of the DBObject interface causes
compiler crash
//===============================================

// The following line causes fatal error C1001
DBObject ^o = gcnew DBObject;

DBObject ^p = nullptr;
// The following line causes fatal error C1001
Handle h = p->HHandleHandle;
}
};
}

This is the simplest example I've found to reproduce the error. Both trivial
and more complex use of the DBObject interface compiles and executes as
expected with C#. This would seem to indicate a bug in the C++ compiler.

Has anyone else seem this kind of behavior?

Thanks in advance for any assistance.

Can you post the errors you're getting?

Thanks,

DotNetBug.h(43) = "DBObject ^o = gcnew DBObject;" as shown in the example
code. As previously mentioned, it seems that any use of the DBObject
interface causes C1001.

Doh! I didn't notice you already had the error in the title of your
post. Apologies :)

This is obviously a compiler bug. Please report it to Microsoft product
support and we'll be happy to provide you with either an acceptable
workaround or a fix. You will not be charged for the support call since
you're reporting an actual bug.

Thank you for your feedback.
