Ack (I won't likely have a fix soon)

I believe this is the same issue as https://github.com/lief-project/LIEF/issues/733 which was fixed by https://github.com/lief-project/LIEF/pull/734. Could you try to test the latest commit?

I just test the script and use radare2 to analyze the generated PE file, it seems the problem still exists.
