Source: libsigc++-2.0 Version: 2.4.1-2 Looking at the build logs at https://buildd.debian.org/status/package.php?p=libsigc%2B%2B-2.0&suite=sid I note that on arm64 this package was built with build-essential_11.7 and g++-4.9, unlike on the other architectures, which used g++-5. Is this deliberate, or an accident resulting from some kind of lagginess? If it's the latter, is there an easy way of detecting which other packages might be affected?
(This isn't really a bug in the source package, but I can see that this package is being actively maintained so thought this would be a good way to contact someone who can get this fixed, if it is a problem. I've already written to ar...@buildd.debian.org about a similar possible problem with cairomm. If this is all being automatically monitored and will be fixed in due course, then sorry for the noise.)
