  *    http://seclists.org/vulnwatch/2005/q1/0088.html
  *
  * This test simply reads each archive image into memory, pokes
  * random values into it and runs it through libarchive.  It tries
  * to damage about 1% of each file and repeats the exercise 100 times
  * with each file.
  *
  * Unlike most other tests, this test does not verify libarchive's
  * responses other than to ensure that libarchive doesn't crash.
  *
  * Due to the deliberately random nature of this test, it may be hard
  * to reproduce failures.  Because this test deliberately attempts to
  * induce crashes, there's little that can be done in the way of
  * post-failure diagnostics.
