Segmentation fault upon finding hash - Si2006 - 03-31-2013
Why am i seeing a segmentation fault upon find hash? in lite version.
Both lite and plus work fine, but i'm having a hard time trying to get pyrit to work with gpu because of AMDAPP.
I had both hashcat/pyrit working nicely until my HD died and had to do a reinstall and now i can remember what i did, I'm sure it will come back to me but that's and problem for elsewhere.
Really it's about the segmentation fault, though i don't see a major issue with it since i can still crack regardless, it's just a niggle i would like to get rid of, is it just bug with hashcat?
