AFL not creating .cur_input file

[Dylan McBean-Kyle [Google]]

I'm trying to fuzz a windows binary in WSL, when I run this command afl-fuzz -V 30 -W -D -i tests/in/ -o tests/out/ -- build/bin/release/winafl_test.exe @@ I get an error of Fork server handshake failed.

when I re run the command with AFL_DEBUG set to 1 I get this output

[-] Hmm, looks like the target binary terminated before we could complete a
handshake with the injected code. You can try the following:

    - The target binary crashes because necessary runtime conditions it needs
      are not met. Try to:
      1. Run again with AFL_DEBUG=1 set and check the output of the target
         binary for clues.
      2. Run again with AFL_DEBUG=1 and 'ulimit -c unlimited' and analyze the
         generated core dump.

    - Possibly the target requires a huge coverage map and has CTORS.
      Retry with setting AFL_MAP_SIZE=10000000.

Otherwise there is a horrible bug in the fuzzer.
Poke <afl-...@googlegroups.com> for troubleshooting tips.

this is saying that there is a format error. but its calling it all correctly. I then went to go and check if that cur_input file was there and it was not. all the other file where in the output directory but not that one. I even deleted everything in the output folder and re ran in case it was somehow like liking stuff being in there and it was still not creating the file.

any ideas? the version of afl-fuzz im using is afl-fuzz++4.06a
