new operator

I was playing around with new operators when I noticed something cool and unexpected. If you return a function the new operator will not create a new object instance but instead return a function. This means that stuff like:

new new new new new new function f(){return f}

Is perfectly valid code. That made me think maybe it would cause a crash. Yep course it does on IE:
eval(Array(0xffff).join('new ')+'function f(){return f}')

Just a stack overflow, I don’t think it’s exploitable but lets try and manipulate it further. Using unicode escapes changes the code slightly:

eval(Array(0xffff).join('\\u006e\u0065w ')+'function f(){return f}')

I then thought about using different types of spaces and fuzzed them but had no success producing any form of exploitable crash, maybe you can?
