#9215: Infinite loop when `any` constructor called for `const any&&`
------------------------------+------------------------
 Reporter:  apolukhin         |      Owner:  nasonov
     Type:  Bugs              |     Status:  new
Milestone:  Boost 1.55.0      |  Component:  any
  Version:  Boost 1.54.0      |   Severity:  Regression
 Keywords:  any const rvalue  |
------------------------------+------------------------
 Code at line 70 in boost/any.hpp must look like this:
 {{{
         template<typename ValueType>
         any(ValueType&& value
             , typename boost::disable_if<boost::is_same<any&, ValueType>
 >::type* = 0 // disable if value has type `any&`
             , typename boost::disable_if<boost::is_const<ValueType>
 >::type* = 0) // disable if value has type `const ValueType&&`
           : content(new holder< typename remove_reference<ValueType>::type
 >(static_cast<ValueType&&>(value)))
         {
         }
 }}}

 Test case:
 {{{
 #include <boost/any.hpp>
 #include <string>

 const boost::any getBoolVal()
 {
     return false;
 }

 int main()
 {
     boost::any vals[] = {1.0, std::string("1m"), getBoolVal()};
 }
 }}}

 Thanks to Bo Peng for finding this issue!
