cnt->current_image because a dangling pointer after image_ring_resize because it is pointing to cnt->imgs.image_ring which is reallocated in that routine. motion_loop will then store cnt->current_image in old_image which it can then read from. Reallocations are rare, once in init to size 1, then once to the final size. I apparently have a bad USB link and I was seeing a crash pointing to bad data, after that camera started, then had an error and crashed in process_image_ring(cnt, IMAGE_BUFFER_FLUSH); it hadn't yet resized to the normal ring buffer size. That got me trying valgrind with a ring buffer size limit of 1 which found this bug.
