Package: src:libphonenumber Version: 8.13.51+ds-4 Severity: important Tags: patch User: debian-de...@lists.debian.org Usertags: icu76
The package fails to build with icu 76.1-2 from experimental. The most likely reason is that it's not built for the default C++17 standards, and manually specifies an earlier standard.
The build log shows the package building with -std=c++14, and failing. Patch at http://launchpadlibrarian.net/769143420/libphonenumber_8.13.51+ds-4build1_8.13.51+ds-4ubuntu1.diff.gz
