--- Comment #5 from Dale Weiler <weilercdale at gmail dot com> ---
I should note that there is a byte in-between these two pieces of code I
removed

     for (; j < i; j++) block.as_bytes[j] = argv[0][j];
     block.as_bytes[j] = 0x01; // I removed this line
     while (++j & 7) block.as_bytes[j] = 0;

Just to make the repro smaller, but I guess that causes that one byte to be
uninitialized in this case. Adding it back doesn't change anything, but it
should be noted it exists here.
