Exception in constructor of cv::cuda::Stream

[rrrand]

System information (version)

• OpenCV => 4.2, 4.5-pre (c8ebe0e)
• Operating System / Platform => Ubuntu 20.04
• Compiler => g++-8.4.0

Detailed description

Exception occured in constructor of cv::cuda::Stream after caught exception from cv::cuda::warpPerspective (see issue #2361).

Exception in cv::cuda::warpPerspective was processed.
terminate called after throwing an instance of 'cv::Exception'
  what():  OpenCV(4.5.0-pre) /home/user/projects/opencv-4.5-builddir/opencv-master/modules/core/src/cuda_stream.cpp:303: error: (-217:Gpu API call) an illegal memory access was encountered in function 'Impl'

Steps to reproduce

Code based on example from issue #2361

// main.cpp

#include <cstdlib>
#include <opencv2/cudawarping.hpp>
#include <vector>
#include <iostream>

int main() {
  cv::Size inputSize{1000, 1000}; // can be different

  cv::Size outSize{670, 893};
  std::vector<double> values{
      0.3154414342519155,    0.2158186507123098,    133.1013012869572,
      -0.01298153793321658,  0.5681477441984867,    297.7284881948252,
      1.839213382549264e-05, 0.0006366310508410327, 1};

  cv::Mat matrix{cv::Size{3, 3}, CV_64FC1, values.data()};

  try {
    cv::cuda::GpuMat image{inputSize, CV_8UC4};

    cv::cuda::Stream stream;
    cv::cuda::warpPerspective(image, image, matrix, outSize, cv::INTER_LINEAR,
                              cv::BORDER_CONSTANT, cv::Scalar{0, 0, 0, 0},
                              stream);
    stream.waitForCompletion();
  }
  catch (const cv::Exception&) {
    std::cerr << "Exception in cv::cuda::warpPerspective was processed." << std::endl;
  }

  cv::cuda::Stream newStream;    // Exception!

  return EXIT_SUCCESS;
}

4.2

We don't support outdated versions.
Try latest code from the master branch first.

@alalek
I've tested on current master (4.5-pre, c8ebe0e). The problem still remains. And the problem #2361 also remains.

[alalek]

Thank you for update!

Looks like this problem is the same and related to warpPerspective() CUDA implementation bug.

Closing as "duplicate".

@alalek
I absolutely agree that these two issues are related. But they are not the same. Exception in constructor is awful! And it should not just be closed!
At least it must be mentioned in original issue. Do you think I should do it?

There is automatic cross-reference link in original issue.

Please try to build and run OpenCV CUDA tests (to ensure that CUDA runtime works).

Thank you! Now I see.

There is automatic cross-reference link in original issue.

Could you please explain what exactly should be tested? I need to check that CUDA rutime works before or after exception? Or I should launch a separate test application?

[alalek]

Build and run opencv_test_cudaimgproc test application.
