Content
buf[1] contains NUL if SIZE_OF_WCHAR_T is 4. The man page says: size_t wcstombs(char dest, const wchar_t src, size_t n) The conversion can stop for three reasons: 3. The wide-character string has been completely converted, including the terminating L'0円'. In this case the conversion ends in the initial state. The number of bytes written to dest, exclud- ing the terminating '0円' byte, is returned. To me this sounds like there cannot be an invalid write.
