[boost] Question regarding Boost.Any storage guarantees

How important is it that assertion below always be true? (Or stated 
negatively, how difficult would life be if it were sometimes not true?)

   template <typename T>
   void f(any & a1, any & a2)
   {
     T* p1 = any_cast<T>( &a1 );
     T* p2 = any_cast<T>( &a2 );

     assert( p1 == 0 || p1 != p2 );   // ***
   }

Thanks,
Eric
