Why is an Array being allocated in the iOS packaged app but not in the Flash version?

When running on my iPad Mini (2nd gen) with iOS 7.1, Scout is telling me that each call to the method drawChild allocates an Array. However, when I run the app as Flash that function makes no allocations. Can anyone tell me what could be allocating memory in that function? Also, has anyone else seen the iOS version of their app have different allocation behavior than the Flash version?

Here is the function in question: https://github.com/LLK/scratch-flash/blob/master/3d_render_src/DisplayObjectContainerIn3D. as#L446-L636

And the Scout view (one frame selected):

Thanks,
