[Boost-users] boost::bind, MSVC7.1 and volatile-qualification

Is there a known problem with boost::bind, volatile-qualified member functions and MSVC7.1? The following snippet of
code happily compiles with various incantations of gcc, but fails with MSVC7.1. The same applies for 'const volatile'.

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

struct TEST
{
        void gv0() volatile;
        void gvc0() volatile const;
        int gv2(int,int) volatile;
        int gvc2(int,int) volatile const;
};

void instantiate()
{
        TEST T;

        boost::function< void() > gv0 =boost::bind(&TEST::gv0,&T);
//	boost::function< int(int,int) > gv2 =boost::bind(&TEST::gv2,&T,_1,_2);
//	boost::function< void() > gcv0=boost::bind(&TEST::gvc0,&T);
//	boost::function< int(int,int) > gcv2=boost::bind(&TEST::gvc2,&T,_1,_2);

}
