I have not been able to reproduce this, even with single-CPU build
systems. I'm building on bookworm with sbuild 0.88.4~bpo12+2 (unshare
backend). The full sbuild command line is
sbuild --build-dir /home/noahm/sbuild \
--chroot=/home/noahm/.cache/sbuild/bookworm-amd64.tar.zst \
--chroot-mode=unshare --dist=bookworm --no-run-lintian \
/home/noahm/spamassassin_4.0.1-1~deb12u1.dsc
I've executed these tests on cloud systems and on bare-metal systems,
with SMP and single-CPU configurations, with 100% success rate.
Can you provide more information about your build environment?
