In case there's anyone else who follows https://buildd.debian.org/status/architecture.php?a=arm64&suite=sid on the look out for interesting errors, a few recent failures seem to be due to https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=795358 ("binNMU C++ libraries built with out-of-date compiler")
For example, this one, 90 minutes ago, seems to be the same thing: https://buildd.debian.org/status/package.php?p=gimagereader&suite=sid It appears that arm-arm-03 was operating with an out-of-date mirror, frozen around Aug 2, till about Aug 9. Does anyone know how that happened and how it could be avoided in future?
