You're right.
However, it would be great being able to fuzz the main logic in libbfd that gas uses so I will try to see how this can be done. Perhaps the smartest is to write the fuzzer as a very simplified version of gas that executes central functions in libbdf - do you have any thoughts on which functions in libbfd would be good to target in this context?
