I'm not sure about this one, but it looks harmless.

This one is definitely harmless. It's caused by the way different
architectures handle a particular optimization in PSPP. The values shown in
the fifth column above are rounded, but the actual values computed are
within double precision of each other (almost), i.e., the difference
is about 1e-15. The actual computed values are something like 0.0049999999999
compared to 0.005000000000001.
