 Fuzzing on a harness compiled with `-DSANITIZERS=address,fuzzer,undefined` is
 good for finding bugs. However, the very slow execution even under libFuzzer
 will limit the ability to find new coverage. A good approach is to perform
-occasional long runs without the additional bug-detectors (just
-`-DSANITIZERS=fuzzer`) and then merge new inputs into a corpus as described in
