Package: src:kamailio Version: 5.3.2-1 [..] The package fails to build in a test rebuild on at least amd64 with gcc-10/g++-10, but succeeds to build with gcc-9/g++-9. The severity of this report will be raised before the bullseye release, so nothing has to be done for the buster release.

The full build log can be found at: http://people.debian.org/~doko/logs/gcc10-20200225/kamailio_5.3.2-1_unstable... The last lines of the build log are at the end of this report.
