ng-if + ng-repeat blocks the script when traceing $index on objectOfObjects

[gp187]

-- using only _ctrl.data.length with _ctrl.data as an object doesn't crash -- only ng-if with ng-repeat AND track by $index :: this is what crashes, with no error

I can't reproduce the crash with your example code: http://plnkr.co/edit/UtXwioP6nE8x8Zxe6Zyj?p=preview

But I also don't see an object of objects in your code.

Weirdly enough I can't replicate it either now. But the behavior was very consistent at the time of issue. If I find it again, I'm posting it with a plunkr
