boost\include\boost-1_53\boost\asio\detail\impl\signal_set_service.ipp Off by One Error

[Oscar Deits <odeits@…>]

In the function

boost::system::error_code signal_set_service::add(
    signal_set_service::implementation_type& impl,
    int signal_number, boost::system::error_code& ec)

The guard statement

// Check that the signal number is valid.
  if (signal_number < 0 || signal_number > max_signal_number)
  {
    ec = boost::asio::error::invalid_argument;
    return ec;
  }

has an Off-by-One error.

The guard statement should read

// Check that the signal number is valid.
  if (signal_number < 0 || signal_number >= max_signal_number)
  {
    ec = boost::asio::error::invalid_argument;
    return ec;
  }
