Could you open a trac ticket on this?
It looks as if multivariate polynomial rings over Integers(p^2) are
directly using Singular,
but I don't think Singu

High,
I installed Miniconda3 and then issued
conda config --add channels conda-forge
conda create -n sage sage python=3.8.5
conda activate sage
and now " sage --version" tells me
SageMath version 9.2, Release Date: 2020-10-24

Small update:
Replacing Integers(p^2) by QuotientRing(ZZ, p^2) seems to fix the issue.

You're now hacking numpy on a 7-year old CPU (that's your Intel(R)
Xeon(R) CPU E7-4830 v2 @ 2.20GHz)...
Probably its AVX support in gcc is a bit broken.
Try
CC="gcc -march=core2" make -j8 numpy
(this should create a numpy build without AVX support)

High,
I upgraded gcc to 10.2.0 but that did not help.

Hello,
I have encountered some strange behavior when I evaluate multivariate
polynomials over the integers modulo n. For instance,
In:
p = 3
S = Integers(p^2)
R. = PolynomialRing(S)
f = x^2 * y^2
print(f([S(p),S(1)]), f([S(1), S(p)]))
Out:
1 0
while both evaluations should ofcourse be equal to
