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

48 * developed for other tests. */
