As always, you can get the latest beta version from the "develop" git branch. Alternatively, the self-contained source tarball is at http://www.sagemath.org/download-latest.html

This fixes an random (and unlikely) bug where conversions to Givaro gave the wrong result, this might have been the cause of a few different random (and rare) test failures.

There is another random failure at #28817 that is comparatively trivial but hits frequently enough to be annoying on the buildbot, please review.

On Debian testing running on core i7 + 16 GB RAM, after upgrading
9.1.beta4 to 9.1.beta5:

make ptestalllong fails to complete: Doctests interrupted: 2188/3816 files tested. See enclosed ptal.log, which
includes the make ptestalllong standard error (nothing lands in
the regular log file).
serial make testalllong succeeds, resulting in four transient
and four permanent errors:

Testing few optional and external packages, I get

Rerunning failed tests, I get the same:

Will create the ticket for combinat/tutorial.py in a minute. Follow up at https://trac.sagemath.org/ticket/25536

On Ubuntu 18.04 running on a bi-Xeon E5-2623 (8 cores) + 16 GB RAM computer:

- incremental build (with -j16) from 9.1.beta4: OK
- all tests from ptestlong passed

Built from a fresh clone of the develop tree on three macOS systems: 10.13.6 (2017 iMac Pro, 18 core Xeon W), 10.14.6 (2017 MPB, Quad-core Core i7), and 10.15.3 (2019 MBP, 9-core Core i9).

No problems on any systems and all tests (‘ptestlong’) passed.
