Description Mark Macdonald CLA 2013-12-05 13:54:46 EST 
1. Ensure you're self hosting off of master
2. Open up astManager.js
3. Place the caret at the end of line 50:
> 	// TODO wrap in try..catch to recover from parse errors in initial statements of code
>                                                                                            ^ put caret here
4. Press ENTER
5. A JS error is thrown. The text buffer appears corrupt and editor actions stop stop working.

> Uncaught TypeError: Cannot call method 'substring' of undefined textModel.js:402
> TextModel.getText textModel.js:402
> (anonymous function) textStyler.js:294

I bisected this to the following commit:
