Maximum length of the test input libFuzzer tries to guess a good value based on the corpus and reports it always prefer smaller inputs during the corpus shuffle When libFuzzer itself reports a bug this exit code will be used If indicates the maximal total time in seconds to run the fuzzer minimizes the provided crash input Use with strcmp
