I can reproduce the error locally. Verbose flag exposes the specific
failing tests:

I've logged the error upstream.
Since dolfin is considered deprecated (superseded by dolfinx), I don't
expect the problem to be solved upstream (alternatively, the problem
can be considered fixed already: test_function.py is passing for
dolfinx).
So I'll work around the problem by skipping test_function.py in the
MPI python unit tests.
The test passes in single process mode. It's only under MPI that the
test fails. These unit tests aren't directly designed to to run with
MPI. Running them with MPI would just provide additional evidence of
robustness, if they would all pass, but the failure here exposes the
limits of that "robustness" stress-testing.
