Overthrow crashing iOS Safari 6.0

I'm having a strange issue with Overthrow. If I include the Overthrow script, my site crashes on my iPod touch's Safari 6.0 (iOS 6.1.3 10B329). If I remove the script, the site works fine. (I have tried the same removal-trial with the few other assets on the site, and Overthrow seems to be the culprit.)

I have not been able to reproduce the crash on Xcode simulators. Previously, I had the same crash on an iPad's iOS7; but when I made other efforts at optimizing, linting, validating, etc., that crash stopped happening.

I have pasted below a log of the crash. I'm afraid I don't know what this stuff means, and searched for help to no avail --- so I'm hoping you know more about this than I do (more than nothing?).

If it helps at all, this is the site I'm having the trouble with: http://davidtheclark.github.io/scut/
