NULL instead of 0, please.

I'd prefer char **argv;

Loop stops when either array element is null.  That's wrong, we need to
exhaust both arrays: || instead of &&.

|| is not safe.  After one array is exhausted, [j] will be out of bounds for
the other.  The g_assert_null calls guarantee the arrays are the same length
and all elements have been compared.
