OpenCV Matcher - std::bad_alloc exception - c++

Question

I'm trying to stitch together some images to make a sort of panorama. I'm using OpenCV so first thing to do is detect keypoints and descriptors than matching them. To do that I'm following this tutorial: http://opencv.itseez.com/doc/user_guide/ug_features2d.html
But during debug I get a std::bad_alloc exception relative to this line:
matcher.match(descriptors1, descriptors2, matches);
Somebody can help me with that? Because I cutted & pasted the tutorial and there are no compilation errors.
Thanks.

Complete code:
Mat img1 = imread(argv[1], CV_LOAD_IMAGE_GRAYSCALE);
Mat img2 = imread(argv[2], CV_LOAD_IMAGE_GRAYSCALE);
if(img1.empty() || img2.empty())
{
printf("Can't read one of the images\n");
return -1;
}
// detecting keypoints
SurfFeatureDetector detector(400);
vector<KeyPoint> keypoints1, keypoints2;
detector.detect(img1, keypoints1);
detector.detect(img2, keypoints2);
// computing descriptors
SurfDescriptorExtractor extractor;
Mat descriptors1, descriptors2;
extractor.compute(img1, keypoints1, descriptors1);
extractor.compute(img2, keypoints2, descriptors2);
// matching descriptors
BruteForceMatcher<L2<float> > matcher;
vector<DMatch> matches;
matcher.match(descriptors1, descriptors2, matches);
// drawing the results
namedWindow("matches", 1);
Mat img_matches;
drawMatches(img1, keypoints1, img2, keypoints2, matches, img_matches);
imshow("matches", img_matches);
waitKey(0);
Update:
if I run this code, I get a:
Run-Time Check Failure #2 - Stack around the variable 'keypoints1' was corrupted.
Code:
#include "opencv\cv.h"
#include "opencv\highgui.h"
using namespace cv;
using namespace std;
int main()
{
Mat img1 = imread("Chessboard1.jpg", CV_LOAD_IMAGE_GRAYSCALE);
Mat img2 = imread("Chessboard3.jpg", CV_LOAD_IMAGE_GRAYSCALE);
if(img1.empty() || img2.empty())
{
printf("Can't read one of the images\n");
return -1;
}
FastFeatureDetector detector(50);
vector<KeyPoint> keypoints1;
detector.detect(img1, keypoints1);
return 0;
}

You need ensure that the following "Additional Dependencies" under the the Properties->Linker->Input are referring to the correct OpenCV libraries with debugger support.
i.e.
C:\OpenCV2.2\lib\opencv_calib3d220d.lib
C:\OpenCV2.2\lib\opencv_core220d.lib
C:\OpenCV2.2\lib\opencv_features2d220d.lib
C:\OpenCV2.2\lib\opencv_highgui220d.lib
C:\OpenCV2.2\lib\opencv_imgproc220d.lib
instead of
C:\OpenCV2.2\lib\opencv_calib3d220.lib
C:\OpenCV2.2\lib\opencv_core220.lib
C:\OpenCV2.2\lib\opencv_features2d220.lib
C:\OpenCV2.2\lib\opencv_highgui220.lib
C:\OpenCV2.2\lib\opencv_imgproc220.lib
