App crashes because of a cvAddWeighted(...) statement

[Shishir]

I'm using OpenCV in native code for my Gingerbread app, and it's crashing at the statement cvAddWeighted(...)

        cvSetImageROI(image2,faces1);//faces1 is of type CvRect
        IplImage *temp1 = cvLoadImage(filepath1);
        IplImage *temp2 = cvCreateImage(cvSize(faces1.width,faces1.height),temp1->depth,temp1->nChannels);
        cvResize(temp1,temp2);
        cvAddWeighted(image2,alpha,temp2,beta,0.0,image2);//cvCopy(temp2,image2);//
        cvReleaseImage(&temp2);
        cvReleaseImage(&temp1);
        cvResetImageROI(image2);

I tested the code only for values of alpha and beta that satisfies beta = 1.0 - alpha, and the app crashes. I found out that it crashes because of the line cvAddWeighted by commenting out the entire block, and then uncommenting one successive line at a time. I also replaced the cvAddWeighted() call with a cvCopy(), but even then the app crashes. Any idea why?

Check if `temp2` has the same `depth` and `nChannels` as `image2`.

Checked, all the images have the same depth, number of channels and all images are BGR images.
