Not too long ago I did a survey of smart pointer variants with respect to this 
issue (for std::auto_ptr, std::unique_ptr, boost::unique_ptr, and 
std::tr1::shared_ptr) and you might find it useful:


I didn't include QSharedPointer because I did not know about it at that time 
(someone linked me to it after the post).

But I saw in Thiago's followup that it worked for him.  So I'm not going to try 
it just now until there's resolution on which compiler + Qt version doesn't do 
it.  But if that is resolved I'm happy to add a  QSharedPointer example to the 
article with whatever caveats are appropriate.
