Floodfill gives different results on different machines

- OpenCV version: 3.1 - Host OS: Mac OS X 10.11.4 Issue in imgproc -> Floodfill function I have a method that uses floodfill function on an image. The issue is that I get different results when running the code on different machines, even with same opencv version. Has anyone else experienced this issue? I can't figure out what is causing this. original image:  Mac OS X EI Capitan, OpenCV version: 3.1:  Ubuntu 14.04.4 LTS, OpenCV version: 3.1:  floodFill( blurredImage, cv::Mat(), cv::Point(blurredImage.cols/2,y), cv::Vec3b(255,255,255), 0, cv::Scalar::all(1), cv::Scalar::all(1) , 8 | 255<<8 );
