+From 480b6fa3662ba8ffeee274bf0d37423413c01e55 Mon Sep 17 00:00:00 2001

+Subject: [PATCH] readelf: Sanity check verneed and verdef offsets in
+ handle_symtab.
+
+We are going through vna_next, vn_next and vd_next in a while loop.
+Make sure that all offsets are sane. We don't want things to wrap
+around so we go in cycles.
