[Bug 2028196] [NEW] Current libzstd fails tests when using dpkg-buildpackage

[Markus Ueberall]

Public bug reported:

When trying to rebuild the current libzstd package on mantic, "dpkg-
buildpackage -us -uc -ui -F" fails to execute the tests.

Output (excerpt):

TBH, I find it rather *unnerving* that the tests fail on Mantic given that this package/compressor is used for e.g. compressing all sorts of archives/backups. (Originally, I tried to rebuild this on Focal and Jammy on x86_64/aarch64/riscv64 hosts and attributed the error shown above to outdated packages, but the above environment is IMHO "as clean as it gets" and the tests *still* fail.)
Shouldn't "dpkg-buildpackage" /always/ work (including passing the enclosed tests) when you rebuild an 
officially released package from the main repository in a clean environment when all dependencies are in place?
Of course, I see that (a) the two weeks old build log (from https://launchpad.net/ubuntu/+source/libzstd/1.5.5+dfsg2-1ubuntu2/+build/26392646) does not show the above error and (b) Mantic isn't a stable release--but this begs the question, whether something changed in the meantime and whether this also might affect the use of the current zstd build.

(The previous package version 1.5.4+dfsg2-5 builds flawlessly in all
aforementioned environments.)
