Thanks, Jaap.

It looks like %llu resolves the problem, at least on this platform.  I
thought it'd be something like that, though it looked like sprintf was
actually writing the same value twice, so it didn't seem like a sizing
issue (I figured I'd see the values from the upper and lower 32-bits.
But now that I think about it more, I think it's starting to make
sense.
