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/202504/

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 add an affects on src:tiff, so that this is still
visible in the BTS web page for this package.

Note 1: This mode of failure also happens in the buildds:

https://buildd.debian.org/status/fetch.php?pkg=tiff&arch=s390x&ver=4.7.0-2&stamp=1743145235&raw=0

https://buildd.debian.org/status/fetch.php?pkg=tiff&arch=armhf&ver=4.7.0-2&stamp=1743145229&raw=0

Note 2: This is apparently a concurrency problem. The makefile in the "tests" directory
is simply not ready to be executed in parallel. The attached patch fixes the issue for me,
by running dh_auto_test with --max-parallel=1. On virtual machines with 2 CPUs, it used to
fail 40% of the time. After applying the patch, it does not seem to fail anymore
(tried 50 times for those statistics).

Note 3: You might want to forward this upstream anyway.

Thanks.
