I am trying to run a chessboard detection with the following code:
std::vector<cv::Point2f> Checker::FindCorners(const cv::Mat& img) {
std::vector<cv::Point2f> corners;
int flag = 0;
flag |= cv::CALIB_CB_EXHAUSTIVE;
flag |= cv::CALIB_CB_ACCURACY;
auto found = cv::findChessboardCornersSB(img, inner_corners, corners, flag);
return corners;
}
When findChessboardCornersSB is executed, I got the following error in the output:
[ERROR:1] global
/Users/rnd/Downloads/opencv-4.3.0/modules/core/src/ocl.cpp
(3874) createFromBinary OpenCL error
CL_INVALID_VALUE (-30) during call:
clCreateProgramWithBinary
The code does not crash and I got the expected result, still I want to solve this error. Can anyone tell me why this error shows and how to solve it?
UPDATE 1:
I did some testing on my own and the error does not show on first run after a restart. When I run the code for a second time this error shows or a GPU hang occurred:

I also ran the code on another PC and this PC shows the same issue.
UPDATE 2:
I am running the code on MacOS Mojave, version 10.14.6. The system has an 2.6GHz Intel Core i5 CPU and a Intel Iris 1536 MB GPU
I ran cv::getBuildInformation() and it shows the following output:

I also ran the OpenCV_test_calib3d, which contains this function. The test passed until the findChessboardCornersSB test is executed, here I get the same error as in my own code:
