Test case

[Brett Wilson (Google)]

I tested this with r41860 on Intel Mac.

[Aaron Golden]

I'm not seeing this assertion with r46406.

Crash is not happening on the latest code, But "Hello" is not coming in the chrome as well as the latest webkit build code, But it is working fine on FF.
So need to check in webkit..

[Deepak Mittal]

I have checked the behavior using :

<!DOCTYPE html>
<html>
	<body>
		<div style="width:0px; height:0px; -webkit-transform:rotate(30deg); transform:rotate(30deg);background-color:red;">
			<span style="font-size:50px; background-color:blue;">Hello</span>
		</div>
	</body>
</html>

and 

<!DOCTYPE html>
<html>
	<body>
		<div style="-webkit-transform:rotate(30deg); transform:rotate(30deg);background-color:red;">
			<span style="font-size:50px; background-color:blue;">Hello</span>
		</div>
	</body>
</html>

behavior is same in chrome,latest webkitcode and FF, and crash is not happening anymore . So we can close this issue
