#12615: any_cast should use addressof instead of operator &

     Type:  Bugs              |     Status:  new
Milestone:  To Be Determined  |  Component:  any
  Version:  Boost 1.61.0      |   Severity:  Problem
 Keywords:                    |
------------------------------+---------------------
 Please see attached test.cpp file for sample code. I have included
 compiler errors in the form of comments in the same.

 If a class has overloaded operator & then any_cast (which uses & itself)
 results in following type of compilation error.

 {{{
 any.hpp:246:16: error: cannot initialize return object of type
 'ExampleClass<int> *'
 with an rvalue of type 'const int **'
 }}}


 I think fix is to replace use of & operator with std::addressof.
 I have attached diff of changes to any.hpp which worked with clang++.
