Possible to continue fuzzing despite errors? #90

Open sudden6 opened 2 years ago

Hi,

Is there a setting to continue fuzzing and ignore crashes? Possibly deduplicating the crashes?

Currently the fuzzer stops at the first found crash, but this is not very helpful if there are multiple possible crashes.

Unfortunately this setting isn't available right now.

@jonathanmetzman WDYT?

libFuzzer doesn't really do well at continuing fuzzing after a crash. And using deduplication here goes against the "lite" philosophy behind CFLite. So if we were to continue fuzzing it would have to be with other fuzz targets. That is basically being asked for in https://github.com/google/clusterfuzzlite/issues/85 I plan to implement that requested feature by mid March

Thank you, Jonathan
