Segmentation fault in (Bag Of Words)

I'm trying to implement bag of words in OpenCV. Basically for now JUST for testing, I have used only 4 images (which you will see in my code below). everything seems to be cool and smooth but when I reach to

BOWImgDescriptorExtractor bowide(&extractor, &matcher);

my compile is successful but when I run the test I got Segmentation Fault, which I think, it might be the problem in inserting the images or something else..

Any advice?

From the docs for BOWImgDescriptorExtractor it looks like extractor and matcher should be held in Ptrs, something like (untested):

Ptr<DescriptorExtractor> extractor(new SurfDescriptorExtractor);
...
Ptr<DescriptorMatcher> matcher(new BruteForceMatcher<L2<float> >);
BOWImgDescriptorExtractor bowide(extractor, matcher);
