[Boost-users] [bind, regex] strange MSVC 7.1 compiler effect: Members of unnamed namespace are put in boost::re_detail when stdafx.h includes bind.hpp and regex.hpp

Hi there,

I have a strange compiler effect with Microsoft Visual Studio.NET 2003 and boost 1.33.1 in a project that uses bind and regex. All Symbols defined in an unnamed namespace are part of the namespace boost::re_detail::'anonymous-namespace'.
The effect occurres when I use precompiled headers and bind.hpp is included before regex.hpp.

This is my stdafx.h which is used to generate the precompiled header:

    #pragma once

    #include <boost/bind.hpp>
    #include <boost/regex.hpp>

This is the main source file:

    #include "stdafx.h"
    #include "boost/current_function.hpp"

    namespace {
        void foo( void )
        {
                printf( "%s\n", BOOST_CURRENT_FUNCTION );
        }
    }

    int main( int argc, char * argv[] )
    {
        foo();
        return 1;
    }

The program generates this output:

    void __cdecl boost::re_detail::`anonymous-namespace'::foo(void)

instead of the expected output:

    void __cdecl `anonymous-namespace'::foo(void)

When I change the include order in stdafx.h so that regex.hpp is included before bind.hpp the output is as expected.
Has someone else came across such a problem? Is it a compiler bug?

Regards,
        Stefan
