--- Comment #7 from Luke Kenneth Casson Leighton <lkcl at lkcl.net> ---
ha, hilarious

    overflow <- ((prod[0:32] != 0x0_0000_0000) &
                 (prod[0:32] != 0x1_ffff_ffff))

that's in hexadecimal, which is 36 bits long, not 33.  so the
pseudocode rightly complains.

i changed it to [0]*33 and [1]*33 and that works.
