So, it really looks like it is only showing the top-level library calls (bindresvport) and syscalls (open, read, write), but not the intermediary library calls (strtoul)

Also, further tests showed that even using spaces rather than tabs won't work. In order for the blacklist file to be parsed correctly, it'd need 

Btw, the bug is marked "Incomplete" right now. What does that mean exactly?
