fandango on core n.
[Unix/C hackers, from the Iberian dance] In C, a wild pointer
that runs out of bounds, causing a core
dump, or corrupts the malloc(3) arena in such a way as to cause mysterious
failures later on, is sometimes said to have `done a fandango on
core'. 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
