Comment:

 The problem is not in av_crc, but in shuffleplanes. It's not propagating
 the palette plane despite being a pal8 stream.

 ./ffmpeg -i PoC_seg_crc_403.tga -vf shuffleplanes,showpalette -f null -
 ./ffmpeg -i PoC_seg_crc_403.tga -vf shuffleplanes -f apng -y /dev/null

 All fail the same way, trying to access AVFrame->data[1], which is NULL.
