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?

Weird indeed, I don't believe it's our problem as such: except that both regex and bind use unnamed namespaces. Looks like the poor compiler is getting confused :-( John.
