>Description:
The following code (the whole code is in the attatchment):



    list<myclass> mylist;

    for_each(mylist.begin(), mylist.end(),

             bind2nd(mem_fun1_ref(&myclass::f), 2));



where f = "int f(int i)"

produces this message:



/usr/local/include/g++-v3/bits/stl_function.h: In member function `typename

   _Operation::result_type std::binder2nd<_Operation>::operator()(typename

   _Operation::first_argument_type&) const [with _Operation =

   std::mem_fun1_ref_t<int, myclass, int>]':

   _Ret = int, _Tp = myclass, _Arg = int]





(See also bug #470, it seems to relate to this.)



I have tried also an older gcc-snapshot and 2.95.2 (with its own library). They produce the same error.
