Re: try/catch behaviour with SEH (VC++ 8)

Hi there,

I am a little bit confused. I used to think that std C++ exceptions are
mapped on top of SEH with VC++, but it seems it is no longer true. The
following example:

    #define WIN32_LEAN_AND_MEAN
    #include <windows.h>
    #include <iostream>

    void test()
    {
        try
        {
            int *p = 0;
            *p = 0;
        }
        catch ( ... )
        {
            std::cout << "Catched in C++ handler!\n";
        }
    }

    int main()
    {
        __try
        {
            test();
        }
        __except( EXCEPTION_ACCESS_VIOLATION == GetExceptionCode() )
        {
            std::cout << "Catched in SEH handler!\n";
        }
        return 0;
    }

outputs "Catched in C++ handler!" if compiled with VC++ 6 - okay. But
VC++ Express 2005 SP1 warns about unreachable code in the catch(...)
block (warning C4702), and the compiled program outputs "Catched in SEH
handler!".

I am very confused about that, I was really convinced it should work as
with VC++ 6. Does anyone know more about this ?
