Lines 1978 of file FrameView.cpp which potentially caused crash are changed in this cl (frame #2, "blink::FrameView::updateLayersAndCompositingAfterScrollIfNeeded").

I'm unclear; was this clusterfuzz run before or after https://codereview.chromium.org/2720823002/ was submitted ? At first glance I suspect its the same crash as issue 696173 which that CL fixed.
