  "message": "Fix segfault with --cpu-used \u003e\u003d 3 and ext-refs.\n\nWith ext-ref enabled, it is possible that when trying to encode the\nfirst true ALTREF frame after a keyframe, the previous ALTREF frame\n(alias for the keyframe) is the same as one of the new LAST{2,3,4}\nreference frames, and hence cpi-\u003eref_frame_flags will have the ALTREF\nbit clear, as computed by get_ref_frame_flags in encoder.c.\n\nsf-\u003ealt_ref_search_fp forces the previous ALTREF frame to\nbe used as the only possible  reference when encoding a new ALTREF\nframe, but due to cpi-\u003eref_frame_flags, some buffers will not be\ninitialized (see rdopt.c:7689 yv12_mb), leading to a segfault.\n\nget_ref_frame_flags in encoder.c has been changed to prefer to keep\nthe  LAST frame, then the ALTREF frame, then any of the LAST{2,3,4}\nframes and then the GOLDEN frame in that order of preference in case\nany of them are the same. This avoids the segfault and behaves the\nsame for the baseline.\n\nChange-Id: I4da1991667614009da5d3061a6316c0d5dbc6c0c\n",
