Shrinksafe forward reference problem

[guest]

Shrinksafe breaks this code :

function my_object(){
        var a=''
        this.doIt = function(){
                doingIt()
        }
        this.getA = function(){
                return a
        }
        var doingIt=function(){
                a = 'done'
        }
}
var mm=new my_object()
mm.doIt()
alert( mm.getA() )

Here is the shrinked code :

function my_object(){
var a="";
this.doIt=function(){
doingIt();
};
this.getA=function(){
return a;
};
var _2=function(){
a="done";
};
}
var mm=new my_object();
mm.doIt();
alert(mm.getA());

The probleme is that the function "doingIt()" has been renamed "_2" but the call hasn't been renamed. If I reorder "doingIt()" and "doIt()" , the probleme is solved.

I already mentionned and dicussed this problem here :

Ticket #3581 is a duplicate of this bug, providing another context in which variable order is important.

I don't know if this helps or not, but found something interesting in my own 'discovery' of this bug.

This compresses just fine:

  SomeOtherFunction(function() {
    var calculateSomething = function(val) {
      doSomethingInteresting(1, 1, 1);
    };
    var calculateSomethingElse = function(val) {
      doSomethingInteresting(1, 1, null);
    };
    var doSomethingInteresting = function(foo, bar, baz) {
      // some code here...
    };	
  });

But this slightly different version doesn't:

  SomeOtherFunction(function() {
    var calculateSomething = function(val) {
      doSomethingInteresting(1, 1, function(array) { array.push(val); });
    };
    var calculateSomethingElse = function(val) {
      doSomethingInteresting(1, 1, null);
    };
    var doSomethingInteresting = function(foo, bar, baz) {
      // some code here...
    };	
  });

The only difference in this example is the anonymous function being passed in the first function's call of the doSomethingInteresting function.

Hope that helps...
