I have fixed this in the next release but I don't have access to that source
code just now, but it was something like ...

  w32Seed = xor_bits(floor(w32Seed), remainder(peek4u(msg+16), #3FFFFFFF)
  w32Seed = xor_bits(floor(w32Seed), remainder(peek4u(msg+20) *
              peek4u(msg+24), #3FFFFFFF))
