Boost C++ Libraries: Ticket #3022: Automatic conversion from Y* to boost::shared_ptr with std::pair

Peter Dimov — Wed, 13 May 2009 19:25:27 GMT

This is caused by std::pair's converting constructor:

template<class U, class V> pair<T1, T2>::pair( U const & u, V const & v ):
  first( u ), second( v ) {}

and, unfortunately, there is nothing shared_ptr can do to stop it.

Sorry, I meant:

template<class U, class V>
  pair<T1, T2>::pair( pair<U, V> const & r ):
  first( r.first ), second( r.second ) {}

The initialization of second (of type shared_ptr) from r.second (or type int*) is explicit and as such, it does succeed.

Sorry, I did not think such a constructor exists. I'll check that the next time. Should I resolve the Bug or is this usually done by the maintainer?
