ippiFilterMin_16u_C1R crashed (IPP 8.2)

Could you please point me where I made a mistake doing ippiFilterMin_16u_C1R? Demo code below.
Thanks.

        ippInit();
	
	int mskSizeX = 3;
	int mskSizeY = 3;
	IppiSize roi={(int)imageW - (mskSizeX - 1),(int)imageH - (mskSizeY -1)}, mask={mskSizeX,mskSizeY};
	IppiPoint anchor =  {mskSizeX/2, mskSizeY/2};

	int stepBytes;
	int stepBytesf;
	Ipp16u* d_image1 = ippiMalloc_16u_C1(imageW, imageH, &stepBytes);
	Ipp16u* d_image2 = ippiMalloc_16u_C1(imageW, imageH, &stepBytes);
	Ipp16u* d_image11 = ippiMalloc_16u_C1(imageW, imageH, &stepBytes);
	Ipp16u* d_image22 = ippiMalloc_16u_C1(imageW, imageH, &stepBytes);


	ippiCopy_16u_C1R(h_average_noload,stepBytes,d_image1,stepBytes,roi);
	ippiCopy_16u_C1R( deviceListReal->at(frameSlider->value()).data(), stepBytes, d_image2, stepBytes,roi);
	
	IppStatus  a  =ippiLShiftC_16u_C1IR(4, d_image1, stepBytes, roi);
	IppStatus  b = ippiLShiftC_16u_C1IR(4, d_image2, stepBytes, roi);
	
	ippiFilterMin_16u_C1R( d_image1, stepBytes, d_image11, stepBytes, roi, mask, anchor ); ///exception here

Ok..

Ok..

Hi, It looks the image

Hi, It looks the image border is not handled correctly in the code, basically, for some filter functions, image need to have border prepared for calling the function. You can check this article for a few details:
