deleting shared memory c++

[yer_averagejoe]

Hi, i've drawna bit of a blank on this one..

say i have an object class like this:

class Object{

public:
   ...
   ~Object();
   void SetMaterial(Material *m)

protected:
   Material* materialPtr;
};

Object::~Object(){
   if(materialPtr){
      delete materialPtr;
      materialPtr = NULL;
  }
}

void Object::SetMaterial(Material *m){
   materialPtr = m;
}

And I declare two objects with the same material like so:

Material* Material = new Material();
Object* Object1 = new Object();
Object* Object2 = new Object();

Object1->SetMaterial(Material);
Object2->SetMaterial(Material);

When the objects get destroyed, each object tries to call the material destructor.. breaking the program. How would i fix this? Any help appreciated

nm, that was a bad way of doing things. I've got a material manager type thing going on now
