What do you have for ``` $ ulimit -a core file size (blocks, -c) 0 data seg size (kbytes, -d) unlimited scheduling priority (-e) 0 file size (blocks, -f) unlimited...

On prefix I have ``` max user processes (-u) 257289 ``` I'm unable to change `uname -u` on Gentoo (no sshing involved) ``` ulimit -u 127294 bash: ulimit: max user...

Same failure on Prefix as [above comment](https://github.com/cschwan/sage-on-gentoo/issues/610#issuecomment-731690660) after upgrading to `symmetrica-3.0.1`. `user processes` on Prefix is twice what you have. There must be some component that's doing this.

Doctesting vanilla 9.3.beta1 using all available Gentoo components as ``` sage -tp 5 --long --all --memlimit=0 ``` gives the failures ``` sage -t --long --warn-long 223.1 --random-seed=0 src/sage/doctest/test.py # 29...

On gentoo prefix, where I have symbols compiled in, I have ``` Cython backtrace ---------------- #0 0x00007f98d795e4e0 in __GI___wait4 () at /storage/strogdon/gentoo-rap/var/tmp/portage/sys-libs/glibc-2.32-r2/work/glibc-2.32/posix/../sysdeps/unix/sysv/linux/wait4.c:30 #1 0x00007f98d2417ab1 in print_enhanced_backtrace () at /storage/strogdon/gentoo-rap/var/tmp/portage/dev-python/cysignals-1.10.2/work/cysignals-1.10.2/build/src/cysignals/implementation.c:563 #2...

In Gentoo prefix this ``` sage -t --long ~/usr/lib/python3.8/site-packages/sage/doctest/test.py ``` now passes with `openblas-0.3.9-r1` where I has 29 failures with `openblas-0.3.12-1`

My openblas ``` [U] sci-libs/openblas Available versions: 0.3.9-r1^t 0.3.10^t 0.3.12-r1^t {dynamic eselect-ldso index-64bit openmp pthread +relapack test} Installed versions: 0.3.9-r1^t(12:36:42 PM 11/23/2020)(eselect-ldso openmp -dynamic -index-64bit -pthread -test) Homepage: http://xianyi.github.com/OpenBLAS/ Description:...

All tests passed for ``` sage -t --long ~/usr/lib/python3.8/site-packages/sage/doctest/test.py ``` in prefix with `sci-libs/openblas -openmp pthread`. The doctest failed miserably with the useflags switched. This was with 0.3.12
