--- Comment #1 from dodji at redhat dot com ---
This seems to be fixed by a recent commit to the master branch of the
repository.

I have just tested it with this commit
https://sourceware.org/git/gitweb.cgi?p=libabigail.git;a=commit;h=18d535ba7f10edc03901f5a85c90f6516b18e594
and here is the result:
