--- Comment #15 from Fujii Hironori <Hironori.Fujii at sony.com> ---
WebCore::Animation is a RefCounted object that is thread-unsafe.
TextureMapperAnimation was shared between the main thread and
ThreadedCompositor thread. WebCore::Animation object should be
cloned and TextureMapperAnimation should have an isoleted copy of
WebCore::Animation. Zan's patch (Bug 166923 comment 1) was aiming
that.

r248406 (Bug 200533) changed TextureMapperAnimation to have
RefPtr<TimingFunction> instead of RefPtr<WebCore::Animation>, and
call TimingFunction::clone(). I think this crash was fixed by
r248406.
