<div>
<pre>It appears that the website is running out of stack space while making a virtual call to a Javascript function for the first time. The call to the function properly fails due to out of stack space, but we try to add the function to a polymorphic cache and it doesn't have a CodeBlock. linkPolymorphicCall crashes without a CodeBlock.
We need to make linkPolymorphicCall() properly handle a function without a CodeBlock.</pre>
