libxml2 built with gcc 6.5.0
I compiled libxml2 version 2.9.7 (http://www.xmlsoft.org/) with gcc 6.5.0. When
I run abidiff with itself, I get a coredump while I don't get the issue when
the same version of libxml2 is built with gcc 8.3.1
The stack I have:

This is reproducible the libabigail 1.6 linked against the latest elfutils
(0.178).
I attach a reproducer.
Simply run:
> abidiff libxml2.so.2.9.7 libxml2.so.2.9.7
