--- Comment #3 from Ulya Trofimovich <skvad...@gmail.com> ---
The "uninitilized" error is simple: the code assumes nonempty array and sets
its first element (in the case of a zero-sized array it adds one element, which
causes the second error because the assumption that there is an even number of
elements in the array is broken). The following simple patch fixes the error:
