The test animations/needs-layout.html is a flaky image failure on macOS Sierra. It has failed on WK1 release and WK2 Debug.
The test seems to have been flaky from when it was added.
I was able to reproduce the failure in Sierra debug with:
run-webkit-tests animations/needs-layout.html --debug --no-retry-failure --iterations=50 -f
This is a new test, just added in bug 172300. Dean, can you take a look please?
Marked test as flaky:
This failure has since started on El Capitan Debug and iOS Simulator Debug:
This test is now flaky on release, too.

This crash should not be related to this patch which only affects the code path used for the new animation engine. This test uses the legacy animation engine and the ASSERT reached in FrameView is conditioned to only run on the legacy code path, so we are indeed not using the new one.
