Core dumped or Im doing something wrong? - rmonico - 09-22-2016

Hi everybody!

Im learning how to use hashcat, when I run on my machine:

Code:
hashcat --status --status-timer 10 --opencl-device-types 1 -a 3 -m 0 <md5 hashcode of three letter here> ?l?l?l

I get:

Code:
hashcat (v3.10) starting...

Is it a bug or am I doing something wrong? If its a bug, how can I provide more information to help solve this?
Im using Manjaro Linux (same repos from ArchLinux), my OpenCL driver is AUR's intel-opencl-runtime.

Thanks in advance!

Since clinfo is not part of hashcat but crashing too I'd say your OpenCL installation is broken. You need to fix that first.
