cuda::remap - illegal memory access

[gyzcode]

System information (version)

• OpenCV => 4.4.0
• Operating System / Platform => Windows 64 Bit / ubuntu 18.04 amd64
• Compiler => Visual Studio 2019 / gcc 7.5.0

Detailed description

For some specific data, the cpu version remap works fine, but the cuda version remap can not work. The error message is as follows: OpenCV(4.4.0) Error: Gpu API call (an illegal memory access was encountered) in cv::cuda::device::imgproc::RemapDispatcherNonStream<Filter, B, T>::call, file D:/programming/ opencv_contrib-4.4.0/modules/cudawarping/src/cuda/remap.cu, line 107

Steps to reproduce

map data to reproduce:map.zip

// C++ code example

#include <opencv2/opencv.hpp>
#include <opencv2/cudawarping.hpp>

using namespace cv;
using namespace cv::cuda;

int main(int argc, const char** argv)
{
    FileStorage fs("D:/map.yml", FileStorage::READ);
    Mat map1, map2;
    fs["map1"] >> map1;
    fs["map2"] >> map2;
    fs.release();

    Mat src, dst;
    src = Mat(640, 640, CV_8UC3, Scalar(255,255,255));
    cv::remap(src, dst, map1, map2, INTER_LINEAR);

    imshow("dst", dst);
    waitKey();

    GpuMat gsrc, gdst, gmap1, gmap2;
    gmap1.upload(map1);
    gmap2.upload(map2);
    gsrc.upload(src);
    cuda::remap(gsrc, gdst, gmap1, gmap2, INTER_LINEAR);
    gdst.download(dst);

    imshow("gdst", dst);
    waitKey();

    return 0;
}

Issue submission checklist

• [x] I report the issue, it's not a question
• [x] I checked the problem with documentation, FAQ, open issues, answers.opencv.org, Stack Overflow, etc and have not found solution
• [x] I updated to latest OpenCV version and the issue is still there
• [x] There is reproducer code and related data files: videos, images, onnx, etc
