Thanks for this release candidate!

On Ubuntu 20.04 running on Xeon E5-2623 + 16 GB RAM:

- incremental build (-j16) from Sage 9.6.beta7 with system python (3.8.10): OK

- make ptestlong --> "All tests passed!"

Eric.

In particular, the failures with the 4 files involving GLPK made a bug in doctest/parsing.py appear:

On Debian testing running on core i7 + 16 GB RAM, upgrading 9.6.beta7 to 9.6.rc0 and running ptestlong gives no failure at all.

HTH,

On a slightly different machine (Debian testing, core i5, 8 GB RAM), upgrading 9.6.beta6 to 9.6.rc0 and running ptestlong results in two permanent failures :
