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.
