Adobe Flash: XML and XMLNode classes missing constructor type check

[GoogleCodeExporter]

The XML and XMLNode classes are missing type checks in their constructors. If a 
class extends a class that sets the object user data, and its constructor 
contains the following code, type confusion can occur on garbage collection.

        super();
        this.__proto__={};
        this.__proto__.__constructor__ = XML; //Or XMLNode
        super("test");

This bug is subject to a 90 day disclosure deadline. If 90 days elapse
without a broadly available patch, then the bug report will automatically
become visible to the public.
