Segmentation fault [core dumped] by any execution.

Hi guys,

i was trying to execute hashcat using my GPU's and i got a "segmentation fault" error, i don't know what i'm doing wrong. I was googling for a similar issue but i didn't find anything. 

Nvidia drivers

Code:

Then i tried to use a specific device, and i got the same issue.

Any suggestion ?.

Thanks !


Update

i downloaded an old hashcat version and it worked. its a bug ?, should i report it formally ? .

Code:
