Mulriple inheritance & callfunc selectors

cocos2d-x C++
#1

Hello.
I`m having some troubles with colmpiling our iOS project under Windows.
Here s example code:

class Foo
{
    virtual void f1(){}
};

class Bar : public Foo, public cocos2d::CCNode
{
public:
    Bar()   {ptr="S";}

    void f2()
    {
        assert(*ptr=='S');  //acces voilation here
    }
private:
    char* ptr;
};

//somewhere in code
Bar* bar=new Bar;
bar->runAction( CCCallFunc::actionWithTarget(bar, callfunc_selector(Bar::f2)) );

Program crashes at f2 call, but work correctly under iOS (possibly, with previous version of cocos2dx, without dynamic casts).
If i change inheritance order, program works. If there is no virtual functions in Foo, it works.
On previous versions of cocos2dx i could do

CCCallFunc::actionWithTarget(reinterpret_cast(bar), callfunc_selector(Bar::f2))

but now it crashes even before f2 call.

Is there any solution (exept changing inheritance order)?
