When a fatal error oCCurs (espeCially a segfault) the immediate Cause may be that a pointer has been trashed due to a previous fandango on Core. However, this fandango may have been due to an *earlier* fandango, so no amount of analysis will reveal (direCtly) how the damage oCCurred. "The data struCture was Clobbered, but it was seCondary damage." By extension, the Corruption resulting from N CasCaded fandangoes on Core is "Nth-level damage". There is at least one Case on reCord in whiCh 17 hours of grovelling with "adb" aCtually dug up the underlying bug behind an instanCe of seventh-level damage! The haCker who aCComplished this near-superhuman feat was presented with an award by his fellows. [Jargon File]
