Adobe Flash - Use-After-Free in Sprite Creatio

Code
Source: https://bugs.chromium.org/p/project-zero/issues/detail?id=718

There is a use-after-free in Sprite Creation. If a Sprite is created, and then the handler for the frameConstructed event triggers a remove object action, the Sprite is then used after it has been freed.

A sample swf is attached.
