PVS-Studio warning V668 for Angle

VertexDataManager::VertexDataManager(Renderer *renderer) :
  mRenderer(renderer)
{
  ....
  mStreamingBuffer = new StreamingVertexBufferInterface(
    renderer, INITIAL_STREAM_BUFFER_SIZE);

  if (!mStreamingBuffer)
  {
      ERR("Failed to allocate the streaming vertex buffer.");
  }
  ....
}

This suspicious code was found in Angle project by PVS-Studio static code analyzer.
Warning message is:
V668 There is no sense in testing the 'mStreamingBuffer' pointer against null, as the memory was allocated using the 'new' operator. The exception will be generated in the case of memory allocation error. vertexdatamanager.cpp 69
