I can confirm this is fixed by libabigail 1.4, which marks this as a harmless
change automatically.

Yes, it is.  I think we should flag this change as harmless.

Thanks for pointing this out.

[Bug default/23629] New: Libabigail thinks GLib broke ABI

            Bug ID: 23629
           Summary: Libabigail thinks GLib broke ABI
           Product: libabigail
           Version: unspecified
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: default
          Assignee: dodji at redhat dot com
          Reporter: bochecha at daitauha dot fr
                CC: libabigail at sourceware dot org
  Target Milestone: ---

Over at the Freedesktop-Sdk project, we're using abidiff to check for ABI
breaks of our whole SDK.

Updating GLib from 2.56. to 2.58, abidiff reports the following:

  Functions changes summary: 0 Removed, 1 Changed, 0 Added function
  Variables changes summary: 0 Removed, 0 Changed, 0 Added variable

  1 function with some indirect sub-type change:

    [C]'function void g_clear_object(volatile GObject**)' at gobject.c:3381:1
has some indirect sub-type changes:
      parameter 1 of type 'volatile GObject**' changed:
        in pointed to type 'volatile GObject*':
          in pointed to type 'volatile GObject' at gobject.h:187:1:
            entity changed from 'volatile GObject' to 'typedef GObject' at
gobject.h:187:1
            type size hasn't changed

This was a deliberate change in GLib:
https://gitlab.gnome.org/GNOME/glib/commit/2aacef39b1cfe4cc5eade704db05ffe1516be22e

Could this be a bug in libabigail, that this isn't considered a harmless
change?

Actually, it seems like libabigail 1.4 actually flags this as harmless.
But then it looks like I forgot to update the libabigail package in
Fedora 28.   The update should reach that distro soon, i.e:
https://bodhi.fedoraproject.org/updates/FEDORA-2018-0f1a9b9137.

Sorry for the inconvenience.
