Actually, afaik BITS_PER_ULL == BITS_PER_BITS_WORD
Ah, OK, thanks for following up. It looks like the negated-comparison bug caused undefined behavior due to integer overflow in count_one_bits_word; once that happens it's anybody's guess what compilers will do; maybe you hit the jackpot. Anyway, the Emacs bug is fixed (and there doesn't seem to have been a compiler bug) so I'll close this report.
