C++ - How to break when the number of references to a shared pointer change?

Question

In Microsoft Visual C++ 2015, how can I set a "Data Breakpoint" on a Boost shared pointer so that the debugger breaks whenever the number of strong and/or weak references changes?

The control block of a std::shared_ptrin VS2015 has _Usesand _Weaks members. Just set data breakpoints to these through their watch expressions: e.g. &(*(ptr)._Rep)._Weaks
