I was wondering if there's interest in a smart pointer, which is able to cope with circular references. I think it would make a nice addition to the smart_ptr classes already in boost.
The code I have aims to solve this problem, by using two types of pointers. The execution thread will work with boost::intrusive_ptr (which are allocated on the stack) while classes wishing to point to other classes, will use a new type of pointer (named 'reference') that I designed. This pointer is aware of the owner of the pointer, in addition of the object it points to.
I might be more interested if I more clearly saw your proposed design and solution. Could you provide a brief code example, even if it is just pseudo-code, and detail exactly what the user witnesses (I.e. when destruction occurs, etc.)? As well, what is the "non-standard" initialization you speak of? -- -Matt Calabrese
