--- Comment #1 from Richard Smith <richard-llvm at metafoo.co.uk> ---
If you ask for an array of exactly four characters and initialize it with a
four-character string, you didn't leave any room for a null terminator, so you
don't get one.

C11 6.7.9/14: "Successive bytes of the string literal (including the
terminating null character if there is room or if the array is of unknown size)
initialize the elements of the array."
