Sadly, the same problem: works with msvc 7.1 put not intel 9.0:

error: more than one instance of overloaded function "mem_fn" matches
the argument list:
            function template "boost::mem_fn(R (T::*)() const)"
            function template "boost::mem_fn(R (T::*)())"
            argument types are: (<unknown-type>)

This problem initially came up when I was using boost::bind in this way:

make_transform_iterator(v.begin(), bind(&array_type::at, _1, 0))

Intel 9.0 had these errors:

error: more than one instance of overloaded function "bind" matches
the argument list:
            function template "boost::bind(R (T::*)(B1), A1, A2)"
            function template "boost::bind(R (T::*)(B1) const, A1, A2)"
            argument types are: (<unknown-type>, boost::arg<1>, int)

Thanks,
