package: libstdc++6 severity: serious Hi,
It seems the symbols file for libstdc++6 is missing some symbols on armel. The build adds these with the latest version. This causes new builds that use these symbols to pick up an (unnecessary) versioned dependency on the latest gcc in unstable. As this bug sometimes causes testing migrations to block on the migration of gcc, and thus interferes with transitions, I'm filing this as serious. This currently is the case with the opencv binNMU on armel, which is blocked behind gcc-10, blocking the python3-defauls transition. Maybe the build should we configured to fail when new symbols are discovered, to avoid similar issues in the future. Thanks! Ivo
