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, this can corrupt the OS itself, causing massive
lossage. Other frenetic dances such as the rhumba, cha-cha, or
watusi, may be substituted. See aliasing bug, precedence lossage, smash the stack, memory leak, memory smash, overrun screw, core.
