On Debian testing running on core i7 + 16 GB RAM, I attempted (see there
<https://groups.google.com/g/sage-support/c/IvjMhqryRQs>) to force the use
of Sage-installed pari, which somehow triggered the use of sage’s giac ;
this didn’t solve my (other) problem.
Re-forcing the use of system’s pari and giac and running ptestlong gets me :
sage -t --long --warn-long 232.5
--random-seed=190544560087993084851651335503239842385

src/sage/functions/min_max.py # 2 doctests failed
The last two have been already reported and are cosmetic and numerical
noise respectively. The first one is new, seems related to my
re-installation of giac, and is serious ; it may be related to the problem
I tried to solve elsewhere (in both cases, the problem appears to be raised
in cython code).
Re running it gives :

I’m out of my depth here. Suggestions ?
