#8100: boost::any can't be empty

     Type:  Bugs                           |      Status:  new    
Milestone:  To Be Determined               |   Component:  any    
  Version:  Boost 1.52.0                   |    Severity:  Problem
 Keywords:  content any destructor         |  
-------------------------------------------+--------------------------------
 {{{
 any()
     : content(0)
 {
 }
 ~any()
 {
     delete content;
 }
 }}}

 should be replaced i guess by :

 {{{
 any()
     : content(0)
 {
 }
 ~any()
 {
     if (content != 0)
         delete content;
 }
 }}}

 else an empty boost::any crashes at destruction, and other operations can
 fail like :

 {{{
 template<typename ValueType>
 any & operator=(const ValueType & rhs)
 {
     any(rhs).swap(*this);
     return *this;
 }
 }}}
 if this->content is null then the local any(rhs) after the swap has a null
 content, provoking a fail at destruction.
