Transform object keys causes error #516
Description
Following code throws runtime error:
**Bug №1 **
Input:
var passthrough = (object) => object;
var foo = {foo: 1},
bar = passthrough({bar: foo.foo});
console.log(bar.bar);
Output:
var passthrough = _0x15e948 => _0x15e948;
var _0x1193f7 = {};
_0x1193f7['foo'] = 0x1;
var _0x49746f = {};
_0x49746f['bar'] = foo['foo'];
var foo = _0x1193f7, bar = passthrough(_0x49746f);
console['log'](bar['bar']);
After extraction {bar: foo.foo} object is inserted before foo variable declaration
Bug №2
Input:
var passthrough = (object) => object;
function test (foo = {foo: 1}, bar = {bar: foo.foo}) {
return bar.bar;
}
console.log(test());
With this code, looks like maximum call stack error will appear
