Summary:
When attempting to print out a UIView.transform in LLDB when running on an ARM64 device, LLDB gives a EXC_BAD_ACCESS.

Steps to Reproduce:
1. Create a breakpoint in any iOS project running on an ARM64 device (in my case, an iPhone 6)
2. Enter the following command in the debug console: `p (CGAffineTransform) [theView transform]`

Expected Results:
LLDB should print out the transform.

Actual Results:
LLDB prints out the following:

error: Execution was interrupted, reason: EXC_BAD_ACCESS (code=1, address=0x20).
The process has been returned to the state before expression evaluation.

Version:
Xcode 7 GM

Notes:
I've attached a project that has a shared breakpoint that triggers this issue. If you build and run the project on an ARM64 device, you should see the EXC_BAD_ACCESS in the console, whereas if you run it on a ARMV7 or the Simulator, it works as expected.

Configuration:
This doesn't happen in the Simulator, or on an iPod Touch 5th gen, but it does happen on an iPhone 6, so ARM64 may be the relevant/contributing factor here.
