Bug calling _iter metametoth after creating Array or Object

[jespa007]

This causes a segmentation fault

class A{
	constructor(){
		this.iter=[]._iter();
	}
}

(new A())

The output code is the following,

ScriptFunction: '@MainFunction'

Segmentation fault (core dumped)

As a solution could be do not call _iter just after creation (i.e NEW_ARRAY or NEW_OBJECT instruction)
