Travis Vitek commented on STDCXX-343:
-------------------------------------

This is a source incompatible change. Technically this should be rescheduled for 5.0. Discussion

> The resolution of issue 541 adds an explicit specialization for std::auto_ptr<void>
with the following definition:
> template<> class auto_ptr<void>
> {
> public:
>     typedef void element_type;
> };
> See http://www.open-std.org/jtc1/sc22/wg21/docs/lwg-defects.html#541
> This needs to be implemented (since otherwise the specialization has undefined behavior
-- see STDCXX-172).
