If you go with references, what would happen in this situation:

try
{
//Some client code.
throw some_error(); //Note that this exception does not have exception_info
associated with it.
}
catch(some_error& e)
{
exception_info& info(get_exception_info(e)); //The dynamic cast in
get_exception_info returns a null pointer.
}
