Two ideas:

/1/ It could be right and you have not included <memory>

/2/ The name lookup in MSVC is both wrong and flaky.  If you insist on
using this compiler (I have to at work) then you suffer these problems.

Generally if at the top of your implementation file you pull all the
names you are using into global namespace and use the unqualified names
the problem won't manifest.  Vis:

// headers including
#include <memory>

// Using directives including
using std::auto_ptr;

Yes, it looks a bit like Java, but it works with that most popular of
compilers.
