The follow little example illustrates an issue I have with scoped_ptr. I would like to use this to automatically manage destruction of a pointer to and undefined class. It seems that scope_ptr is instantiating its destructor "too early" and complaining about incomplete type for b;
In my view, this should not occur as ~a() isn't defined yet.
The following example fails on vc 7.1 and gcc 3.2
Note that shared_ptr works as one would hope in this context. Is there anyway to adjust scoped_ptr to work here?
IMO this isn't something scoped_ptr should do. There's to much overhead associated with capturing the type at construction. I proposed something for exactly this purpose a while ago: http://lists.boost.org/MailArchives/boost/msg57577.php And I believe Peter Dimov has something similar in the files section. -- Daniel Wallin
