Dear maintainer:

During a rebuild of all packages in unstable, your package failed to build:

[ Note: both "tao-config" and "xenium" fail in a similar way ]

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/202505/

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:tao-config, so that this is still
visible in the BTS web page for this package.

Thanks.
