PVS-Studio warning V668 for Snes9x

bool StateManager::init(size_t buffer_size) {
  ....
  if (!(buffer = new uint64_t[buf_size]))
    return false;
  if (!(tmp_state = new uint32_t[state_size]))
    return false;
  if (!(in_state = new uint32_t[state_size]))
    return false;
  ....
}

This suspicious code was found in Snes9x project by PVS-Studio static code analyzer.
Warning message is:
V668 There is no sense in testing the 'buffer' pointer against null, as the memory was allocated using the 'new' operator. The exception will be generated in the case of memory allocation error. statemanager.cpp 83
