User(s) can reproduce this bug

When using precompiled headers and debug options, a particular construct causes the compiler to produce "fatal error C1001: An internal error has occurred in the compiler."

Details (expand)

Visual Studio 2010 SP1

1. Create an empty project in Visual Studio 2010 SP1
2. Add a new file stdafx.h with the following contents:

template<class x> class test_template {
public: virtual ~test_template(){}
};

test_template<void> test;

3. Add a new file test.cpp with the following contents:

#include "stdafx.h"
class __declspec(dllimport) testclass : public test_template<void> {};

4. In the project properties, navigate to
Configuration Properties -> C/C++ -> Precompiled Headers

Change the "Precompiled Header" option to "Create (/Yc)" and press "Ok"

5. Open "test.cpp" and press Control+F7 to compile it. Observe the output.

If you set the "Whole Program Optimization" option to "Use Link Time Code Generation" (/GL) the file compiles successfully, but if you turn it off the error occurs.

Hello Jason,

Thank you for reporting this issue. We're aware of this bug in our compiler. We have fixed this in the current VC++ compiler that will be available soon publicly in the next major release of Visual Studio.

Thanks,
