Hi Jello, thanks for the interest in winAFL and this feature. Regarding the problem, First of all, we should identify whether there is some problem with winAFL, application or both....

I see, this is very weird. Are you trying client or server-mode fuzzing ?

What about your target function, are you sure that it is correctly set? Can you try to set the number of ```-fuzz_iterations``` in 1?

Ah, and I almost forget about protocol. Is it TCP or UDP?

Ok, It seems like I start understanding what's going on. Correct me if I am wrong. You want winAFL to act as a man-in-the-middle mutate/inject packets on the fly, right?

Ok, I got it. I guess the problem is that WinAFL actually doesn't support this scenario. The network-mode fuzzing functionality is limited for the following two scenarios: 1. winAFL acts...

If you can replace the server (the final one that send response) with winAFL it might work.

Well, it is hard to say without understanding the actual logic of the program and debugging. What I can say for sure that if it is working under drrun/drcov, it...

I have also seen this error recently in file-based fuzzing mode on Windows 10. Please check that your target is correctly running under debug version of winafl. See [this](https://github.com/googleprojectzero/winafl/blob/master/readme_dr.md#using) for...

I see, make sure that it works in debug mode.
