This is not a bug. TR1 3.5 refers to member function pointers, not member data
pointers as in the submitted test case. mem_fn has no result_type for member
data pointers because the constness of the result type depends on the constness
of the argument type; use result_of to get the appropriate result type given
the argument type. See also TR1 DR 10.24 "Mem_fn result_type for pointer to
data member".
