Get exception from ippiFilterGaussianBorder_8u_C1R function

[KimT]

hi,

when I used GaussianBorder function always get exception thrown at some image size.

image : 594x4082(h*w)

kernelSize:3

maxRoiSize:594x4082

compile_mode:debug_X64

IPP version:2020.2.254

exception information:

Exception thrown at 0x00007FF6B64765A0 in xxx.exe: 0xC0000005: Access violation reading location 0x000001CFAE3B6000.

Could you give us the example of the code which we could compile and execute on our end with the latest version of IPP?

I used IPP lib, as you can refer to the pseudo code below:

----------------------------------

unsigned char* src_head = 0, *dst_head = 0;
int flag,bufSize = 0,specSize = 0;
IppiSize IPPRoiSize = { 0, 0 };
unsigned int kernelSize = 3;
unsigned char* buffer = 0;
IppFilterGaussianSpec* pSpec = NULL;

IPPRoiSize.width = 4082;

IPPRoiSize.height = 594;

flag = ippiFilterGaussianGetBufferSize(IPPRoiSize, kernelSize, ipp8u, 1, &specSize, &bufSize);
pSpec = (IppFilterGaussianSpec*)malloc(specSize);
buffer = malloc(bufSize);

flag = ippiFilterGaussianInit(IPPRoiSize, kernelSize, 3.0f, ippBorderMirror, ipp8u, 1, pSpec, buffer);

src_head = head of src image;
dst_head = head of dst image;

flag = ippiFilterGaussianBorder_8u_C1R(src_head, 4082, dst_head, 4082, IPPRoiSize, 0, pSpec, buffer);

I see no problem on my end.

AVX2 bases system. static linking, sequential.

here is the output:
