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 {aliasing bug}, {precedence lossage}, {smash
   the stack}, {memory leak}, {memory smash}, {overrun screw}, {core}.
