Internal Compiler Error using const wchar_t* in inline method by Henri Hein

Hi Henri:
    Which version of VS2012 do you use? The ICE is fixed in RTM version of VS2012.
    However, the compiler will now give the following error:

error C4400: 'const wchar_t' : const/volatile qualifiers on this type are not supported

    When you use 'protected', 'DLog' becomes a public interface of 'CCompilerErrTest' and is put into the generated winmd file, so that other language (like C#) can call it.
    winmd doesn't support 'const' or 'volatile' (it is a C++ specific concept), so the compiler gives the error.
    Also note that, 'wchar_t *' is translated to a by-reference parameter of type 'Platform::Char' in the winmd, which is different from a wide-string in C++. Use 'Platform::String^' if you want to pass string between different winmds.

    If you don't want to expose 'DLog' outside of your winmd, you can use 'private protected' instead of 'protected'.

I was able to reproduce in a small project and attached it. Good luck!

Hi Henri,
    Thanks for reporting the issue.
    Unfortunately, we can't repro the issue following your steps.
    The error message you see is the general message when the compiler hits internal issues and doesn't have enough information for us to further investigate.
    A self-contained repro is appreciated.

    The code we tried:

#include <strsafe.h>
#include <windows.h>

struct S {
    inline void DLog(const wchar_t* str, int ipar = 0)
    {
        wchar_t out[1024];
        StringCbPrintf(out, sizeof(out), str, ipar);
        OutputDebugStringW(out);
    }
};

int main()
{
    S s;
    s.DLog(L"");
}

Sorry, for some reason I did not receive the earlier comments. I did not try to reproduce the problem in a separate project. I thought the message from the compiler would give a clue. I get around it by just not using const for now.

Thank you for submitting feedback on Visual Studio and .NET Framework. Your issue has been routed to the appropriate VS development team for investigation. We will contact you if we require any additional information.

I am currently standing by for an update from you and would like to know how things are going on your end. If you could get back to me at your earliest convenience with information I request, we will be able to make headway towards a resolution. I look forward to hearing from you.

I am having trouble reproducing your issue. Can you share a sample project on which you are seeing this problem?

Thanks
