Segmentation Fault
 

For some reason when 'John the Ripper' in Kali Linux is about to start it displays a message saying 'Segmentation Fault'. Any way of solving this?

A web search for "john the ripper" "segmentation fault" turns up the following:

https://github.com/magnumripper/John...er/issues/3114

Is it of use?

If not, I suggest that you search their github page for "segmentation fault" or "segfault". If that doesn't turn up anything that matches your circumstances, then you can raise an issue on that page.

I've had apps segfault when I forgot to provide a mandatory argument.
in other words, I'd look for the obvious things first before searching github issues.

Please show us the exact commands you used and the full output you got.
use code tags when pasting that here.
