--- Comment #21 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Looking at https://git.lysator.liu.se/nettle/nettle/blob/master/md4.c I see
there:
  bit_count = (ctx->count << 9) | (ctx->index << 3);
  data[MD4_DATA_LENGTH-2] = bit_count;
  data[MD4_DATA_LENGTH-1] = bit_count >> 32;
and thus it initializes everything.
