Shared pointers are used in my code. 

class Exception : public virtual std::exception,public virtual boost::exception

{

   ---

};

class ExceptionTestException : public Exception

{

---

};

boost::shared_ptr<Exception> exceptionptr_t;

try

{

 Boost_Throw_function(ExceptionTestException("Hiii"));

}

catch(...)

{

    boost::exception_ptr  exceptionptr = boost::current_exception();

   try

  {
       boost::rethrow(exceptionptr)

  }

 catch(boost::exception &e)

  {

    //here i need to assign this 'e' to shared pointer but this e is not in heap so then how to assign this e to sharedptr(exceptionptr_t).

    1 way is :

       boost::exception *ep = new ExceptionTestException(e);

     exceptionptr_t(ep);

       here we know that exception_ptr is having ExceptionTestException but in some cases, we dont know which type of excepiton we have in exception_ptr in         runtime.

then how to assign to shared_ptr
