iTunes backup crack too slow

[Drshu]

I've fixed this on GitHub master and created a new beta on https://hashcat.net/beta/

Thanks for reporting!

I used another computer to compile and it worked. But the test speed still twice fast than real crack. 

Code:

hashcat (v5.1.0-719-gd6f21b08) starting in benchmark mode...

Benchmarking uses hand-optimized kernel code by default.
You can use it in your cracking session by setting the -O option.
Note: Using optimized kernel code limits the maximum supported password length.
To disable the optimized kernel code in benchmark mode, use the -w option.
