Confusion with deep copy in linked list

Solved by helios, thanks!

I'm guessing List<ItemType>::data is of type 'ItemType *'. Line 9 is attempting to dereference an uninitialized pointer. The correct way would be
curr->data = new ItemType(*aPtr->data);

Thank you for the response! I am surprised I did not notice it sooner. Everything works as it should now.
