HI Team,
// i have caught exception in exception_ptr and I and trying to convert to
ExceptionPtr_t but I am facing issue at below derived->severity().
* unknown file: error: SEH exception with code 0xc0000005 thrown in the
test body.*

*code snippet is :*
*E*xceptionPtr_t ExceptionHelper::TryGetExceptionPtr(boost::exception_ptr
exception)
{
ExceptionPtr_t result ;
std::string res;
if(!exception) return result;
try
{
boost::rethrow_exception(exception)
*}catch(boost::exception &e)*

*{boost::throw_file::value_type const* throw_file_data =
boost::get_error_info<boost::throw_file>(e);*
*if(* *throw_file_data)*
*{*
*  result = exceptionPtr_t(new
ExceptionWrapper(exception,*throw_filed_data,true))*
*}*
*return result;*

*}*

class Exception : public virtual std::exception, public virtual
boost::exception
{
  protected:
     string what;
    serviorytype m_severity;
 public:
explicit Exception(const std::string& what);
virtual ~Exception() throw() {}
     // we have some member functions like severity(),setseverity(value)...
}
class ExceptionWrapper : public Exception
 {
  private:
    string m_what_inner;
    boost::exception_ptr m_inner;
 public:
   explict ExceptionWrapper(boost::exception_ptr inner,string &what() =
std::string,bool copythrow = true);
  explict ExceptionWrapper(boost::exceptionPtr_t inner,string &what() =
std::string,bool copythrow = true);
 virtual ~ExceptionWrapper() throw(){}
// some methods like severity(),setSeverity(value),.....)
}

I was doing like:

const Exception*  derived = reinterPret_cast<const Exception*>
(&exception)//  here exception is type of exception_ptr
if(derived)
{
  derived->severity();    // here exception is coming...  if i put this
line in try block then its going for catch block  and new exception is
being rasied. if i dont put try
block then *unknown file: error: SEH exception with code 0xc0000005 thrown
in the test body.*
}

Please help me to resolve this issue
