Thanks so much for making this repo @kristoff! I’ve been using afl-kit the past few days and with this i went from 180/sec to 29-30k/sec - around 163x faster now. Previously I was following https://www.ryanliptak.com/blog/fuzzing-zig-code/ and that was enough to help me eliminate all of the crashes from my parser. But its great to see it running faster now after previously trying to figure out how to speed it up. I just pushed those changes in this commit if anyone is curious.
