> The memory leak was triggered on calling generate_deserialize_list_element()
> function when the elements's type is numeric.The memory leak was triggered on
> calling generate_deserialize_list_element() function when the elements's type
> is numeric. The elements have been malloced, but they have not been freed.
> The elements need to be freed after adding in array.
