Hello. During a rebuild of all packages in unstable, several packages failed to build with a similar error message: Compiler ldc2 cannot compile programs. For a sample full build log you can look at the build log for dcontainers in reproducible-builds: https://tests.reproducible-builds.org/debian/rb-pkg/unstable/amd64/dcontainers.html I'm reporting this against ldc because it looks like a bug in ldc, not in the individual packages, but I'm not 100% sure, so please reassign if appropriate. I've put all the packages failing in this way which I found in the affects field. Thanks.
