turing completeness leak

[dominictarr]

hey I found a gap where you can get at Function and then create code full non static code.

var evaluate = require('./');
var parse = require('esprima').parse;

var src = '(function () {}).constructor("var l = 3; while(l--) console.log(l); console.log(Date.now()); arguments.callee()")()';
var ast = parse(src).body[0].expression;
var res = evaluate(ast); //RangeError from stack overflow

console.log(res)

here is the output:

2
1
0
1426154732632
2
1
0
1426154732632
2
1
...
RangeError: Maximum call stack size exceeded

as you would expect.

It's somewhat harder to prevent turing completeness than it is to create it.

Fixed in 2.0.0.
