Trying to build libffado (2.3.0-1) results in the error below, probably related to the upgrade to GCC 7. Anyway, the offending code indeed seems bogus.
There seems to be a lot of recent activity upstream [http://subversion.ffado.org/browser/trunk/libffado] so this may already have been fixed in the svn repo.
