You have to check the individual log files about what exactly the
differences are.
Sometimes the failures are for spurious reasons, for example the
regression test was assuming rows would be returned in one order, but
they were returned in a different order instead, yet the order is not
meaningful to the correctness.
If you build with a non-default block size, for example, you get many
of these types of failures. Verifying that they are all acceptable is
tedious, and I don't know of an easy way to do it.
