Hi Tzvetomir,
I really like this patch set. Great job!
To get it working on my laptop, I had to make the following changes. I
ran this on a new VM which didn't have libbfd and it failed to build.
Then the check wasn't quite working, and it was saying that libbfd
wasn't installed even though it was. Finally, I tested it against a
small program that had numbers in the function name, and I had to
change your sanitizer to not convert numbers into underscores.
Also, all strdup()s need to be tested. But other than that, it looks
great!
Below is the changes I made.
