cvWarpAffine crashes gives Illegal instruction on 64bit Ubuntu 10.04 (Bug #1650)

Hello,

this code keeps crashing on my machine:

#include <opencv/cv.h>

int main()
{
                IplImage* src = cvCreateImage(cvSize(100, 100), IPL_DEPTH_8U, 1);
                IplImage* dst = cvCreateImage(cvSize(100, 100), IPL_DEPTH_8U, 1);

                float m[6];
                CvMat M = cvMat( 2, 3, CV_32F, m );
                int w = src->width;
                int h = src->height;
                cv2DRotationMatrix(cvPoint2D32f(w*0.5f, h*0.5f), 45.0, 1.0, &M);
                cvWarpAffine(src, dst, &M);
                printf("done.\n");
                return 0;
}

I've compiled it on Ubuntu 10.04: 2.6.32-38-generic #83-Ubuntu SMP Wed Jan 4 11:12:07 UTC 2012 x86_64 GNU/Linux with g++ (Ubuntu 4.4.3-4ubuntu5) 4.4.3. I have an Intel Core2Duo L7400 and I am using OpenCV 2.3.1 which I've installed by following your install guide: http://opencv.willowgarage.com/wiki/InstallGuide. This is was gdb says:

With 3 channel images the code works fine.
