--- Comment #3 from Martin Sebor <msebor at gcc dot gnu.org> ---
For strndup POSIX mentions the following application usage:

Implementations are free to malloc() a buffer containing either (size + 1)
bytes or (strnlen(s, size) + 1) bytes. Applications should not assume that
strndup() will allocate ( size + 1) bytes when strlen(s) is smaller than size.
