Last lines of output from: john --test=0 --verbosity=5

I ran `john --test=0 --verbosity=5` from JohnTheRipper@e0e854e01e46e3e58dcec89d0e87b651c448cdff (plus a local patch as suggested in https://github.com/magnumripper/JohnTheRipper/issues/1470#issuecomment-120698629) as a regular non-root user, which made X crash.

The last lines of output from `john --test=0 --verbosity=5`, when run as a regular non-root user):

Comment 7 Dennis Schridde 2015-07-12 09:25:26 UTC 
I am running Mesa 10.6.1 on Linux 4.1.2. Please note that I was also running radeontop 0.8 at the time I ran john and when X crashed.
Comment 8 Dennis Schridde 2015-07-12 09:27:38 UTC 
Unlike with bug #91305 there was no switching to a VT and kernel output this time. X (SDDM+KDE, managed by systemd) immediately restarted.
Comment 9 Dennis Schridde 2015-07-12 09:32:09 UTC 
After this, without rebooting, john will immediately segfault:
```
$ /usr/sbin/john --test=0 --verbosity=5
