Subject: I need some help on self-test procedures

Hi, there are details that I'm missing (or I am doing anything silly). 
Well, alone I will take forever to understand all code involved.

I'm on bleeding 65706a15c488f173e9ce73a695b25cc87120febd, using CPU 
cryptsha512_fmt_plug.c (the same applies to OpenCL version).

Self-test fails using the right hash and succeed with the wrong one [1]. 
But it cracks the right one (as it should) [2].

I doubled check. Please, anyone can spot what is wrong? To test, I used 
--skip when need.

Pot file.
