在opencl2.0中使用enqueueFillBuffer会产生垃圾

 cl::Buffer intermediateBuffer = cl::Buffer(context, CL_MEM_READ_WRITE,
                    distDeviceWidth * distDeviceHeight * distDeviceDepth * sizeof(T));

  cl::Event copyEvent;

  T value = 0;
   try
  {
    queue.enqueueFillBuffer(intermediateBuffer, &value, 0,
                        distDeviceWidth * distDeviceHeight * distDeviceDepth * sizeof(T),
                        NULL, &copyEvent);
  }catch (const cl::Error& error)
  {
    std::cout << "  -> Prolongation class, Problem in enqueue fill buffer" << std::endl;
    std::cout << "  -> " << getErrorString(error) << std::endl;
    exit(0);
  }

  try
  {
    queue.finish();
  }catch (const cl::Error& error)
  {
    std::cout << "  -> Prolongation class, Problem in finishing fill buffer" << std::endl;
    std::cout << "  -> " << getErrorString(error) << std::endl;
    exit(0);
  }
  copyEvent.wait();

但当我从设备读取数据并将其打印到主机上时 enqueueFillBuffer 产生垃圾。我不知道为什么。必须提到的是,我用opencl2.0构建数据。
