Yes, this is an unfortunate side effect of the current mem_fn implementation that relies on overloading tricks instead of enable_if + is_base_of for portability reasons.
Peter, any workarounds, until its' fixed?
Please use int test::* pm = &test::i; bind<int&>( mem_fn(pm), _1) (v.front()); if possible.
