Testing "for that" would be kind of hard and semi pointless,
isn't it?
If it's mismatch of the expected number of times a pointer is
dereferenced between the caller and the callee, I'd imagine that
it will read from and write to random place in memory and would
lead to unpredictable behaviour. If you are lucky you would not
get expected results but if you are unlucky who knows what would
happen.
But the new test makes sure --sort takes intended effect, which
is a good thing.
Thanks.
