Hi,

I upgraded to beta10, and every segfault is now gone. I bet it was an
edge case of forbidding a recent version of some compiler like gcc.
There is only one abortion left
(src/sage/schemes/hyperelliptic_curves/monsky_washnitzer.py
), but it seems to be documented here
https://trac.sagemath.org/ticket/29719#comment:17, because on debian
unstable libflint-dev depends on libflint-2.6.3, and libflint-dev was
recommended in the installation guide for later version than debian buster.

It could be a good idea to ensure flint version to be less than 2.6.3,
as it was done for gcc and gfortran before beta10. How do you think ?
Should I open a ticket ?

I uninstalled this lib from my system, and the test now passes.

I will continue to look at the other failures.

Best,
