Subject: [d-rats] How to debug a d-rats coredump? Hello Everyone,
I've been successfully playing around with D-RATS v0.3.9 beta 3 on Centos 6.10 and I left the program running over night and found it crashed. The last thing I see on the terminal screen is:
--

Here are the various versions of the program's dependencies installed on this machine:

?? pygtk2-2.24.0-1.el6.x86_64
?? python-six-1.9.0-2.el6.noarch

I tried to run "gdb -c core.24111 d-rats.py" but nothing useful came from the backtrace:
