You should check that you included opencv2/nonfree/nonfree.hpp and called cv::initModule_nonfree() (see the answer on the similar question here http://answers.opencv.org/question/411/feature-detector-crash/#420 or http://answers.opencv.org/question/3630/the-detect-feature-of-siftsurf-always-breaks-code/#3636). Please reopen the issue if this will not help you.

That helped, thank you! Didn't know about cv::initModule_nonfree(), I think this should be written in docs.

Sure, this is where you may make OpenCV more user friendly :-) It would be great if you could prepare a pull request with such an improvement for the documentation!
