Hi Andy,
I saw the source code in seed_rng.hpp, I found you use an
uninitialized buffer[] if fopen fails. It often rely on the stack
contents when previous calling function runs, and that is not always
random.

I think UUID does not need to be random, it just need to be uniquely.
So the seed should contains process id, time, MAC address and so on.
