--- Comment #2 from Said Abou-Hallawa <sabouhallawa at apple.com> ---
I was wring about the above call stack. It is just an assertion call stack. But if we comment all the assertion in SVGAnimatedListPropertyTearOff::animValDidChange() and VGAnimatedPathSegListPropertyTearOff::animValDidChange() we get the following crashing call stack which we should hit in a release build:
