      The error is increases because we reduce the const bit
      of txfm

      Fix segfault with --cpu-used >= 3 and ext-refs. · 77d197e6
      Geza Lore authored
      With ext-ref enabled, it is possible that when trying to encode the
      first true ALTREF frame after a keyframe, the previous ALTREF frame
      (alias for the keyframe) is the same as one of the new LAST{2,3,4}
      reference frames, and hence cpi->ref_frame_flags will have the ALTREF
      bit clear, as computed by get_ref_frame_flags in encoder.c.
      
      sf->alt_ref_search_fp forces the previous ALTREF frame to
      be used as the only possible  reference when encoding a new ALTREF
      frame, but due to cpi->ref_frame_flags, some buffers will not be
      initialized (see rdopt.c:7689 yv12_mb), leading to a segfault.
      
      get_ref_frame_flags in encoder.c has been changed to prefer to keep
      the  LAST frame, then the ALTREF frame, then any of the LAST{2,3,4}
      frames and then the GOLDEN frame in that order of preference in case
      any of them are the same. This avoids the segfault and behaves the
      same for the baseline.
