// ISO-IEC-14882 stated in §15.3-16: The exception being handled is rethrown
// if control reaches the end of a handler of the function-try-block of
// a constructor or destructor.


class X
{
 public:
  X ()
  try
  {
    throw int ();
  }
  catch (...)
  {
    // No rethrow! Violates with ISO-IEC-14882 §15.3-16.
    // Same happens for destructor.
  }
};


int main ()
try
{
  X x;
}
catch (...)
{
  std::cerr << "catched exception\n";
