On low-end personal machines without an MMU (or Windows boxes, which have

an MMU but use it incompetently), this can corrupt the OS itself, causing

massive lossage. Other frenetic dances, such as the cha-cha or the watusi,

|

may be substituted. See <a href="../A/aliasing-bug.html"><i class="glossterm">aliasing bug</i></a>,
