Hi, I encountered the same issue. There are two error messages: 1. carma-mock-lightbar-driver: `[FATAL] [1604681781.071918216]: Error opening file: /opt/carma/data/mock_drivers/drivers.bag` 2. platform: `file does not exist [/opt/carma/vehicle/calibration/mpc_follower/calibration.yaml]` I followed the same...

Thanks! I will try it.

Wrong repo:) This mutator alone has no relationship with the genetic algorithm. You may refer to [AFL++](https://github.com/AFLplusplus/AFLplusplus/blob/stable/docs/afl-fuzz_approach.md) for more details

How do you generate the corpus (i.e., files in `testcases/others/js/`)? It seems the mutation operation is applied to an empty grammar tree. The error might be thrown from here: https://github.com/AFLplusplus/Grammar-Mutator/blob/cbe5e32752773945e0142fac9f1b7a0ccb5dcdff/src/tree_mutation.c#L202-L209

+1 for gathering statistics on the mutators I also listed some enhancements in [TODO.md](https://github.com/AFLplusplus/Grammar-Mutator/blob/stable/doc/TODO.md) - Enhance the mutation: incorporate AFL-style mutations into the grammar mutator for havoc stage (Andrea gave...

I see. Thanks for your explanation! This looks pretty useful.

@0x7Fancy Thanks for digging into this issue! Such an old issue lol The fix looks good to me. Please go ahead and create a PR. I will merge it then.

Will get back to you by the end of this week
