Hi All. I see in sources of the boost/smart_ptr library: shared_count object is allocated by shared_ptr via operator new. But I don't want allocate this object on a heap memory, but via my own allocator.

Take a look at synopsis. http://www.boost.org/doc/libs/1_47_0/libs/smart_ptr/shared_ptr.htm#allocator... There is a constructor overload: template shared_ptr(Y * p, D d, A a); As I understand it, this ctor will allocate internal shared_ptr resources using an instance of Allocator A. Can I do that in boost trunk? Or may be in a future versions of the boost? Actually, this raises the question what will happen with boost::shared_ptr after it made to C++11? Is it going to diverge from standard as an additional feature experiment or go hand in hand with C++11 or become obsolete for C++11 compilers? With Kind Regards, Ovanes
