Access violation in ippiWarpBilinear_8u_C1R

[VVaneev]

Hi,
I'm getting an access violation in ippiWarpBilinear_8u_C1R on a specific input:

#include <ipp.h>
#include <stdio.h>

int main()
{
    int w = 31;
    int h = 27;
    const double coeffs[2][4]{
        { 9.2383544637999199e-07, 1.0076604435213838, 0.0012804359286828610, 0.0000000000000000 },
        { 0.00069696970735535211, 0.28268182239410561, 0.96599999949336035, 16.584000247120859 }
    };
    int interpolation = IPPI_INTER_CUBIC;

    IppiRect roi{ 0, 0, w, h };
    int src_step{};
    auto src{ ippiMalloc_8u_C1(w, h, &src_step) };
    if (IppStatus status = ippiSet_8u_C1R(0, src, src_step, { w, h }))
        printf("%dx%d ippiSet_8u_C1R: %d\n", w, h, status);
    int dst_step{};
    auto dst{ ippiMalloc_8u_C1(w, h, &dst_step) };

    int buf_size{};
    if (IppStatus status = ippiWarpBilinearGetBufferSize({ w, h }, roi, roi, IppiWarpDirection::ippWarpForward, coeffs, interpolation, &buf_size))
        printf("%dx%d ippiWarpBilinearGetBufferSize: %d\n", w, h, status);
    auto buf{ ippMalloc(buf_size) };

    if (IppStatus status = ippiWarpBilinear_8u_C1R(src, { w, h }, src_step, roi, dst, dst_step, roi, coeffs, interpolation, (Ipp8u*)buf))
        printf("%dx%d ippiWarpBilinear_8u_C1R: %d\n", w, h, status);

    ippiFree(buf);
    ippiFree(src);
    ippiFree(dst);
}

Tested IPP versions: 2021.10, 2021.7

Vladislav,

here it looks like a problem which we have to investigate and fix if it is the real problem on IPP end.

Could you try to use please try to use LINEAR interpolation mode.

It is only reproduced with IPPI_INTER_CUBIC interpolation.

Vladislav,

the fix of the problem has been added to the IPP version 2021.12 which has been released a few days ago.

see the log with the previous version of IPP ( 2021.11

ipp$ ./a.out

 IPP Version = 2021.11.0 (r0xcd107b02), BuildDate = Jan 30 2024

31x27 ippiSet_8u_C1R: 0

31x27 ippiWarpBilinearGetBufferSize: 472, StatusReturned = 0

Segmentation fault (core dumped)

and the latest version ( IPP 2021.12

IPP Version = 2021.12.0 (r0x9b172c15), BuildDate = Apr 25 2024 

31x27 ippiSet_8u_C1R: 0

31x27 ippiWarpBilinearGetBufferSize: 472, StatusReturned = 0 

31x27 ippiWarpBilinear_8u_C1R: 0
