looks like a Boost bug.
..\libs\bind\test\mem_fn_eq_test.cpp(175): test 'boost::mem_fn(&X::mf0_1) != boost::mem_fn(&X::mf0_2)' failed in function 'int __cdecl main(void)'

This is caused by the linker folding X::mf0_1 and X::mf0_2 into the same function. It is neither a Boost bug nor a compiler bug, just not particularly standard behavior.
Oh, well, it's a bug of the C++ implementation - we might as well say it's a bug in the compiler even though it technically happens at link time. Pointers to distinct functions are not allowed to compare equal, even if most of their code gets folded. -- Dave Abrahams Boost Consulting www.boost-consulting.com
