This is definitely worthwhile to emphasize again. Also, this issue was
mostly prevalent (though not stictly limited to) to older "cp" utilities
that copied files in a specific order, so it didn't show up for the
developers during normal testing.
There are always going to be bugs in code, and having a hard rule about
sticking to older or newer releases is never going to be right in all
conditions. Staying away from the bleeding edge is usually safe, but
you still need to test for your workload to see if it works for you.
That said, it also helps everyone if users report any problems back to the
developers promptly, rather than quietly saying to yourself "this version
doesn't work for me" and going back to the old one. Vladimir reported the
original #7401 problem to the list on April 5, and after some debugging on
this list a problem was opened in Github. Thanks investigation by a number
of people on the Github issue over the weekend, the problem was isolated
to a specific patch (which itself was fixing a different problem), the
patch was reverted, and fixes have already been proposed.
I don't think you can really ask for better behaviour than this. It is
unlikely that a large number of people were seriously affected by this
bug, and with the quick release of 0.7.8 there should be little additional
fallout from this specific issue.
