The above is just how the build ends and not necessarily the most relevant part.
If required, the full build log is available here:

About the archive rebuild: The build was made on virtual machines from AWS,
using sbuild and a reduced chroot with only build-essential packages.

If you could not reproduce the bug please contact me privately, as I
am willing to provide ssh access to a virtual machine where the bug is
fully reproducible.

If this is really a bug in one of the build-depends, please use
reassign and affects, so that this is still visible in the BTS web
page for this package.


Notes:

The tests do not currently work since version 1.3.2-3, see Bug #1085691.
That's why I'm reporting this against version 1.3.2-2.

This happens 100% of the time for me when the machine has one CPU.
The trivial way to reproduce is GRUB_CMDLINE_LINUX="nr_cpus=1".

If this is not expected to work, I suggest applying the attached patch.

However, this used to work in bullseye (joblib 0.13.0-2), which also had
tests called "parallel".

Maybe this should be forwarded upstream to see that they think.

I'd like to backport the fix to bookworm-proposed-updates, but naturally only
after we know what is the good fix (or a fix which is considered good
enough for the team).

Thanks.
