Description Mark Lam 2016-08-11 11:46:09 PDT
The Element object is a test object provided in the jsc shell for testing use only.  JavaScriptCore expects host constructors to either throw an error or return a constructed object.  Element has a host constructor that did not obey this contract.  As a result, the following statement will fail a RELEASE_ASSERT:
    new (Element.bind())

We should fix this.
