I try the following code using OpenCV 2.3.1 and it fails when attempting to return in main(). typedef struct window { int height; int width; double scale; struct window next;
}window; int main() {
CvSVM svm=CvSVM(); svm.load("SVM_DATA2.xml"); IplImage *p=cvLoadImage("C:\1\result2\image_00050.png",-1); struct window *head,q; head=descriptor(p,1.1,svm); for(q=head;q!=NULL;q=q->next) {
cvRectangle(p, cvPoint(q->width,q->height), cvPoint(q->width+cvFloor(64q->scale),q->height+cvFloor(128q->scale)), cvScalar(0,0,255), 1);
}
cvNamedWindow("svm", CV_WINDOW_AUTOSIZE); cvMoveWindow("svm", 100, 100); cvShowImage("svm", p ); cvWaitKey(0); cvReleaseImage(&p ); return 0; } and gives the message (VS2008 Windows 7) OpenCV Error: Assertion failed (udata < (uchar)ptr && ((uchar)ptr - udata) <= (ptrdiff_t)(sizeof(void*)+16)) in unknown function, file ......\src\opencv\mod ules\core\src\alloc.cpp, line 76. So,I tried some break point,when i come to the bottom line" return 0" it shows cv::Exception. I am a freshman and will waiting for any advice.

}

}

and gives the message (VS2008 Windows 7) 7)
