PVS-Studio warning V668 for webrtc

int16_t ACMGenericCodec::InitEncoderSafe(....)
{
  ....
  in_audio_ = new int16_t[AUDIO_BUFFER_SIZE_W16];
  if (in_audio_ == NULL) {
    return -1;
  }
  ....
}

This suspicious code was found in webrtc project by PVS-Studio static code analyzer.
Warning message is:
V668 There is no sense in testing the 'in_audio_' pointer against null, as the memory was allocated using the 'new' operator. The exception will be generated in the case of memory allocation error. acm_generic_codec.cc 568
