BTW. I see two GCC8 related fixes in elfutils git since the last release: commit 268a27211b152d876185ff95255e5025c43b9c13 Author: Mark Wielaard <m...@klomp.org> Date: Mon Nov 20 14:11:02 2017 +0100
libdwfl: Don't dereference possibly unaligned auxv entry pointer from core. The notes in a core file that contain the auxv entries might not be naturally aligned. The code already tried to account for that, but the GCC 8 undefined behaviour sanitizer found we were till dereferencing the actual auxv entry pointer directly. Fix this by calculating all pointers by hand and not use an array of auxv entries trick. This makes make distcheck (which enables sanitize-undefined by default) pass again using GCC8.

The GCC8 -Wpacked-not-aligned warns if a structure field with explicit padding in a packed structure will be misaligned. m68k prstatus core notes are described by a packed structure which has such aligned structure fields.
