Passing Templates through Pointers

[starbucks99]

I'm having an issue with passing templates through pointers, I managed to simplify the issue to this.

So I have a simple template,

template<class T>
class List
{
	public:
		T* Arg1;
		List(T* first){Arg1=first;}
};

Which I run through,

void GetChildren(ListProperties &properties)
{
	List<CPtrList> *list = new List<CPtrList>(properties.children);
	int count = list->Arg1->GetCount();
        Test(list);
}

void Test(void *list)
{
	List<CPtrList>* newList = (List<CPtrList>*)list;
        int count = newList->Arg1->GetCount();
}

The count in GetChildren gets me 1(the correct result), whereas the count in Test gets me a number that's way off (-45030200 or something along those lines).

Can anyone shed some light on where the problem might be?
