 **(100%)** In this lab, you will write a LLVM pass in `llvm-pass/afl-demo-pass.so.cc` & `llvm-pass/afl-demo-rt.o.c` and satisfy the following requirements.
-1. When running afl++ to fuzz `program`, `program` can't crash by `system("echo AAA");` at line 34 in `program.c`. It's not command injection, and you will see the error message below when you try to fuzz:

     ```
     [-] PROGRAM ABORT : We need at least one valid input seed that does not crash!
     ```
     Of course, you can not just detect this line to avoid it. We will modify this command and add additional system functions (which won't cause command injection) in `program.c` during testing with your fuzzer.
