-HEY THIS TEST IS FAILING AND I DONT KNOW HOW TO REPRODUCE IT??
-
-At the point when this file was authored, I had no idea how to get the crash
-artifacts out of bazel/the fuzzer/kokoro/somewhere and onto your machine.
-
-Without that this seemed like a problem - why check whether fuzzers pass if
-we can't debug them?
-
-My thinking is this: if we can find an example that fails within a few minutes
-in CI, we can probably do likewise on your machine.
-
-Try:
-
-bazel build path/to/fuzzer --config=fuzzer_asan -c dbg
-bazel-bin/path/to/fuzzer path/to/fuzzer_corpus -jobs=$CPUS -workers=$CPUS
-
-You should see whatever failure this CI job found before terribly long.
