This looks rather impressive.  Have you considered automatically
detecting duplicates by e.g. analyzing stacktraces?

american-fuzzy-lop kind of does that. It creates a hash among the code
path and groups fuzzing samples by that. That's quite convenient.

Yeah, I think there was even an article in one of recent PLDIs which discussed different approaches to filtering duplicates arising in compiler fuzz testing (they did various combinations of stacktraces, Valgrind output, program coverage, etc.). I was just curious how well this works for real world tasks like objdump crashes.
