9796	std::system_error cannot be catched after is rethrown with boost::rethrow_exception()	anonymous	Emil Dotchevski	"boost::rethrow_exception() loses information about the system_error exception type. See the 
following example code, which when compiled with g++ --std=c++11, displays
''exception caught'' instead of  ''system error caught'':


{{{
#include <iostream>
#include <system_error>
#include <boost/exception/all.hpp>


void do_something()
{
  try
  {
    // let's assume the following exception is thrown inside some
    // system library function...
    throw std::system_error(EDOM, std::system_category());
  }
  catch (...)
  {
    boost::rethrow_exception(boost::current_exception());
  }
}
int main()
{
   try
   {
    do_something();
   }
   catch (const std::system_error & ex)
   {
      std::cout << ""system error caught\n"";
   }
   catch (const std::exception & ex)
   {
      std::cerr << ""exception caught\n"";
   }
   return 0;
