shared_ptr in unordered_set | Microsoft Connect

Posted by Andrew Durward on 9/18/2012 at 12:05 PM

Has this been fixed in the version on which it was reported (i.e. MSVC 2010 SP1)? Or only in MSVC 2012?

If the former, could you provide details about how to obtain the patch? My copy of MSVC 2010 SP1 still does not provide a specialization of std::hash for std::shared_ptr as required by the C++11 standard (sec. 20.7.2.6).

Thanks,
andrew

Try defining a hashing function for ‘shared_ptr’. For example:

using namespace std;

template< typename T >
class hash< shared_ptr< T > > : public unary_function< shared_ptr< T >, size_t >
{
    hash< void * > vh;

public:
    size_t operator () (const shared_ptr< int > & z) const
    {
        return vh(z.get());
    }
};
