Hello.

For me to reproduce the issue and be able to debug it, it's helpful to provide
a command line to reproduce the issue, like 'abidiff binary1 binary2'.

I have downloaded the tarball at https://nanonyme.kapsi.fi/public/glibc.tar.xz.
 Thank you for having provided it.  But then, how am I supposed to reproduce
the problem exactly?

Also, have you tried to reproduce the issue using libabigail from the master
repository?

The libabigail version from master could handle the binaries from the tarball
that your version of libabigail was failing from, if I believe one of the
comments of the bug.  Here is what I did with the current libabigail from
master to test for that:

$ abidw --abidiff glibc/usr/lib/x86_64-linux-gnu/libanl.so.1
$ abidw --abidiff glibc/usr/lib/x86_64-linux-gnu/libnsl.so.1
$ abidw --abidiff glibc/usr/lib/x86_64-linux-gnu/libpthread.so.0
$ abidw --abidiff glibc/usr/lib/x86_64-linux-gnu/libpthread.so.0
$ abidw --abidiff glibc/usr/lib/x86_64-linux-gnu/libcrypt.so.1
$ abidw --abidiff glibc/usr/lib/x86_64-linux-gnu/libutil.so.1
$ abidw --abidiff glibc/usr/lib/x86_64-linux-gnu/libdl.so.2
$ abidw --abidiff glibc/usr/lib/x86_64-linux-gnu/libnss_db.so.2
$ abidw --abidiff glibc/usr/lib/x86_64-linux-gnu/gconv/libJISX0213.so
$ abidw --abidiff glibc/usr/lib/x86_64-linux-gnu/libnss_files.so.2
$ abidw --abidiff glibc/usr/lib/x86_64-linux-gnu/libnss_hesiod.so.2
$ abidw --abidiff glibc/usr/lib/x86_64-linux-gnu/libnss_compat.so.2
$ abidw --abidiff glibc/usr/lib/x86_64-linux-gnu/libthread_db.so.1
$ abidw --abidiff glibc/usr/lib/x86_64-linux-gnu/libc.so.6
$ abidw --abidiff glibc/usr/lib/x86_64-linux-gnu/librt.so.1
$ abidw --abidiff glibc/usr/lib/x86_64-linux-gnu/libresolv.so.2
$

I think that I really need to release what we have in master now so that you
can update to that one instead as there are many many fixes stacked there.
