Фатальная ошибка в libopencv_imgproc.so на cvPyrUp

Question

Я пытаюсь выполнить этот JavaCV код:

IplImage src; // simple image 
IplImage gray = cvCreateImage(cvGetSize(src), IPL_DEPTH_8U, 1); 
cvConvertImage(src, gray, 0); 

CvSize sz = cvSize(gray.width() & -2, gray.height() & -2); 
IplImage pyr = cvCreateImage(cvSize(sz.width()/2, sz.height()/2), gray.depth(), gray.nChannels());   
cvPyrDown(gray, pyr, CV_GAUSSIAN_5x5); 
cvPyrUp(pyr, gray, CV_GAUSSIAN_5x5); // - fatal error on this line   
cvReleaseImage(pyr); 

Для некоторых изображений я получаю сообщение об ошибке (на cvPyrUp):

Я нашел решение https://github.com/bytedeco/javacv/issues/409

IplImage pyrUp = cvCreateImage(cvSize(2*pyr.width(), 2*pyr.height()), pyr.depth(), pyr.nChannels());   
cvPyrUp(pyr, pyrUp, CV_GAUSSIAN_5x5);
