Follow-up Comment #4, bug #35024 (project octave):

I'm a little curious to know what kind of computation is being performed on
Windows that accounts for this difference. It's not the first time we see
Windows getting the last bit of a computation wrong. We frequently have to
increase the tolerance for some of our unit tests because Windows gets it
slightly wrong.

Can someone suggest a reason, or do we have a genuine bug on Windows?
