Research direction
Start by reproducing the failure with the official OpenCV build under multiprocessing fork mode, importing and using cv2.xfeatures2d.matchGMS. Investigate whether the corrupted double-linked list error is reliably triggered in that combination; done means a confirmed fix is identified and verified, or the limitation is clearly documented.
