n. When a fatal error occurs (esp. 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 grovel
ling 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.
