Comment (by fireattack):

 So I assume pix_fmt routine is part of swscale?

 The same problem doesn't seem to happen if format conversion is done in
 {{{colorspace}} using

 {{{ffmpeg -i reference.pnm -vf
 colorspace=iall=bt601-6-625:all=bt709:format=yuv420p -f crc - -vf
 format=bgr24,colorspace=iall=bt601-6-625:all=bt709:format=yuv420p -f crc
 -}}}
