The AFL test failed

I tried the example in Readme and executed the following command:

afl-fuzz -i examples/test-network/in -o ./examples/test-network/out -- ./fpicker --fuzzer-mode afl -e attach -p test-network -f ./examples/test-network/harness.js
[-] 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 <[email protected]> for troubleshooting tips.

Just export AFL_NO_FORKSRV=1 first.
