Ooh, I wasn't trying to say it was too big. I was trying to say it
would be okay to have that on stack. :)

I'm not too sure about this one. First of all, I think %08lx is more
of an accident than intention (just forgot to update it while
transitioning to 64bit) and when ls'd the output can be a bit messy
without leading 0's, but again my opinion here isn't very strong.
