Do you have any examples of where we create a CheapRNG, but don't call seed()?

Log:
seed wasn't being called which resulted in an uninitialized value
for val. This caused tons of warnings in valgrind. It also meant
that val_see remained uninitialized and possibly contained the same
4 values. If you don't want create() to call seed, then make sure
seed is called somewhere else!
