Trying real hard to build a fuzzer targeting the CPython JIT, lots of features implemented but not a single crash or bug discovered so far.

Such is life when hunting for crashes in robust code.

This weekend I'll be spinning off a new fuzzer that grew from fusil. Wish me luck 🙂

@danzin "Any fuzzer at all, no matter how primitive, has a
better chance of finding a bug than an idle CPU core."

Good luck ;)

@buherator Thanks!

The new fuzzer is live and found two JIT crashes, so it's met the goal of being better than an idle core in practice :)
