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.

Description

Under multiprocessing (fork) mode, importing and using from cv2.xfeatures2d import matchGMS in the official OpenCV build occasionally triggers a corrupted double-linked list error. Is there a reliable fix?
