Replying to [comment:42 john_perry]:
> That wasn't smart of me. I looked at them, and they turned out to be
numerical issues; I've seen the first reported elsewhere (0.0 v. -0.0). So
this doesn't strike me as being caused by a change to categories & rings.
I remember that I had the same problem with one of the alpha versions.
By the way: Four days ago, I had updated the patch at #9138. Do you use
the new version? With the old version, one would get an error on
sage.math.
Can you test at what point in the patch chain the test starts to fail, and
report appropriately? That's to say, if it fails with unpatched
sage-4.7.2.alpha2 then report to sage-release; if it fails with #11115 or
#11342 only, then report there.
