Built w/o problems on three macOS systems. Testing with ‘ptestlong'

10.13.6 (2017 iMac Pro, 2.3 GHz Intel Xeon W). Testing got two failures, both intermittent:
sage -t --long --warn-long 67.6 --random-seed=0 src/sage/geometry/polyhedron/base.py # 1 doctest failed
sage -t --long --warn-long 67.6 --random-seed=0 src/sage/graphs/bipartite_graph.py # 1 doctest failed

10.14.6 (2017 MBP, 3.1 GHz 4-core Core i7). Testing got two failures: external.py (log attached as 10.14.txt). One intermittent and familiar; the second reported last time, and seems persistent.
sage -t --long --warn-long 134.4 --random-seed=0 src/sage/geometry/polyhedron/base.py # 1 doctest failed
sage -t --long --warn-long 134.4 --random-seed=0 src/sage/symbolic/integration/external.py # 1 doctest failed


10.15.7 (2019 MBP, 2.4 GHz 8-core Core i9). Testing got one failure:
sage -t --long --warn-long 67.6 --random-seed=0 src/sage/graphs/bipartite_graph.py # 1 doctest failed

Thanks for merging this fix. There's still a small number of tickets marked "critical" (some positively reviewed, some need review) - that would be good to merge: https://trac.sagemath.org/query?priority=critical&status=needs_review&status=positive_review&milestone=sage-9.4&groupdesc=1&group=status&max=1500&col=id&col=summary&col=component&col=time&col=changetime&col=author&col=reviewer&col=keywords&order=component

From the first built on Mac OS 11.5.2 (Intel Core i5), it compiled without problem. 

But <<make test>>  failed :

I am getting an unexpected failure when running the patchbot, but it seems not to be reproducible.

Thanks for this new release candidate!

Here are some testing results on Debian and Cygwin
for `make -s V=0 testlong` or `make -s V=0 ptestlong`
after `./bootstrap -q` and `./configure -q`.

## Debian 10 buster, no optional packages

All tests passed!

## Debian 10 buster, many optional packages

Doctest failures related to permutation groups.
Not clear what combination of optional packages
causes the failures. Ticket:

- Fix failing doctests in groups/perm_gps/permgroup.py
https://trac.sagemath.org/ticket/32294

## Cygwin 3.2.0 on Windows 10, no optional packages

(Thanks to E. Madison Bray for working on Sage
on Cygwin last week. Several lingering doctest
failures became tickets and are now fixed!)

Sage builds. Doctest failures in two files
(observed since Sage 9.3, which was when
I resumed building and testing Sage on Cygwin,
though I did not send any reports until now).

- src/sage/tests/cmdline.py # 3 doctests failed

Fixed by installing the sqlite cygwin package.
This ticket, which needs review, should help:

- Add sqlite3 to sqlite/distros/cygwin.txt
https://trac.sagemath.org/ticket/32399

- src/sage/symbolic/expression.pyx # 1 doctest failed

This ticket, already positively reviewed, fixes it:

- Fix maxima('acosh(0.5)') doctest in expression.pyx
https://trac.sagemath.org/ticket/32401

Thanks to Frédéric Chapoton for pushing a fix.

Looking forward to the next release candidate. --Samuel
