The above is just how the build ends and not necessarily the most relevant part.
If required, the full build log is available here:
https://people.debian.org/~sanvila/build-logs/202506/
About the archive rebuild: The build was made on virtual machines from AWS,
using sbuild and a reduced chroot with only build-essential packages.
In this particular case, the build was made on AWS machines of type
m7a.medium and r7a.medium. Incidentally, those machines have a single CPU,
but at this point it's not clear yet if that's the condition which triggers
the build failure or, for example, the fact that they are overall slower
than other instance types, or maybe some other reason.
If you could not reproduce the bug using GRUB_CMDLINE_LINUX="nr_cpus=1"
please contact me privately, as I am willing to provide ssh access to a
virtual machine where the bug is fully reproducible.
Disclaimer: Please note that this is probably a violation of
Debian Policy 4.2, and the only reason I'm initially reporting
it as "important" is to avoid discussing about the severity.
If this is really a bug in one of the build-depends, please use
reassign and add an affects on src:numba, so that this is still
visible in the BTS web page for this package.
Note: In some similar cases the only reasonable fix is
to "import os" and skipif(os.cpu_count() == 1) the affected test.
Thanks.
