    Log Message:
    SHA256Final: skip zero-length pad memset at block boundary (CID 645972)

    When the 0x80 terminator lands on the last byte of the block, buf_off
    advances to SHA256_BLOCK_SIZE and the subsequent memset is called as memset(buffer + 64, 0, 0). The size-zero call is harmless, but forming
    a one-past-the-end pointer trips Coverity's OVERRUN checker. Guard the
    memset on buf_off < SHA256_BLOCK_SIZE; behavior is unchanged.
