hashkill crashes when cracking a zip file #6

Closed kholia closed 11 years ago

Most likely the problem is in restoring session state.

Removing ".hashkill" folder didn't fix the problem. hashkill started working again after a reboot. I am not sure why hashkill was crashing earlier.

Hello kholia,

Do you remember the session id that crashed upon restore?

gat3way commented 11 years ago

I just noticed you were using -t1. gpu-platform was not stored in the session file which caused various....strange effects. With the latest commit, it is already stored. Could you please retry with the newest files from the git repo?

I haven't been able to reproduce the problem with latest git code (dae016dda9).
