PVS-Studio warning V596 for MTASA

bool String::grow(size_type new_size)
{
  // check for too big
  if (max_size() <= new_size)
    std::length_error(
      "Resulting CEGUI::String would be too big");
  ....
}

Most likely this is what should be written here: throw std::length_error("Resulting CEGUI::String would be too big");

This suspicious code was found in MTASA project by PVS-Studio static code analyzer.
Warning message is:
V596 The object was created but it is not being used. The 'throw' keyword could be missing: throw length_error(FOO); ceguistring.cpp 59
