Hello, There was an interesting post today [1] on Hacker News about fuzzing Rust with american-fuzzy-lop (AFL). Interestingly the AFL instrumentation gets applied as LLVM pass. I started to wonder if it would be possible to do the same with Haskell binaries? I know there are plenty of tools designed specifically for Haskell but still it might be interesting to see how AFL performs in this setting.
