cvPyrUp上libopencv_imgproc.so中的致命错误

Question

I try to execute this JavaCV code:

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);

For some images i get an error message (on cvPyrUp):

I found the solution 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);
