That's an unusual one... Which Linux?

Is it completely reproducible? It is extremely unusual to have such crashes and RHEL 6 is a common platform, so I don't have any clear idea, to be honest... Try saving the script and running "atkpython script.py" from the command line. Although, I don't expect that to work differently...

Ok... We will need your help in troubleshooting this. It could be related to ATK, or it could be localized to your machine, but to find this out, please follow the steps below. Start by downloading the attached script atkpython_debug onto your Linux machine. You will probably need to give it executable permission:
Code
chmod +x atkpython_debug
Save a simple test script, like the Ag fcc calculation you indicated before, as a file, let's call it ag.py. Put it in the same directory as atkpython_debug. Then open a terminal, and navigate to the directory where you saved the scripts. At the prompt, type
Code
./atkpython_debug ag.py
The script will automatically perform "run", "bt", and "quit" in gdb (the GNU Debugger). When it finishes you are left at the prompt again - send us the information it printed; this will allow us to learn more about this problem.

I apologize for not studying the gdb command line options better. I have amended my post above to show a better way.

With every script do that mean that you see this error every time you run this script or does it mean that any script no matter what gives this error?
