Hello The problem was due to an old version of libfa present in /usr/local/lib. augparse was loading this old incompatible version.
Once this library is removed, augparse works normally. You can close this bug. Sorry for the noise. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org
