Comment (by kurosu):

 Could you relaunch, and type info register? Then 'up' (to get back into
 mpeg_motion_internal) and then 'print dest_y', ptr_y and linesize?

 The issue is most probably an unaligned address, but I'd like to see more.

 This is by the way what you would have done, if you had followed:
 https://www.ffmpeg.org/bugreports.html

 It's not crashing here, though.
