Hi,
I can reproduce this locally, even on a amd64 arch. Simplest file that shows the issue is

$ cat file.py
from dolfin import *
mesh = UnitSquareMesh(2, 2)
print([c.volume() for c in cells(mesh)])


and produces the expected result on python 3.12 but not on python 3.13

$ python3.12 file.py
[0.125, 0.125, 0.125, 0.125, 0.125, 0.125, 0.125, 0.125]

$ python3.13 file.py
[]

Not sure yet what is going wrong here, maybe memory not being allocated correctly by pybind11 due to changes in python 3.13?

Cheers,
Francesco
