[Bug 1794544] Re: [SRU] 2.56.3

[Iain Lane]

This upload should *fix* misbuilds for future builds. It itself
shouldn't cause things to break and/or unbreak (unless there was
breakage inside glib2.0 itself, in which cause I would have expected one
or more of the rdeps' tests to have picked the problem up already).

On the upstream issue that resulted in that particular fix somebody came
up with a reproducer, but upstream we are not aware of any cases in the
wild where anything was tripping over this. (Not that we would
necessarily be, of course.)

I've added a note to watch out for the autopkgtests that'll be triggered
by this upload. As I say though, I would have expected that if this bug
was breaking applications then we'd already have known about it by
failing tests or bug reports.

** Description changed:

  [ Description ]
  
  The third stable release in the 2.56 series.
  
  [ QA ]
  
  Upstream release, so QA already performed by maintainers
  
  https://wiki.ubuntu.com/StableReleaseUpdates/GNOME
+ 
+ This upload will trigger many autopkgtests that we expect to not be
+ regressed by this upload.
  
  [ Regression potential ]
  
  Various fixes in multiple places so multiple apps could be affected.
  
    * New upstream release (LP: #xxx)
      + The documentation for G_GNUC_MALLOC has changed to be more restrictive
        to avoid miscompilations; you should check whether any uses of it in
        your code are appropriate
      + Fix cancellation of g_subprocess_communicate_async() calls
      + Bug fixes:
        + /network-monitor/create-in-thread fails in (LXC) containers on glib-2-56
        + GBookmarkFile: nullptr access in current_element
        + GBookmarkFile: heap-buffer-overflow in g_utf8_get_char
        + Backport g_subprocess_communicate() cancellation fixes from !266 to
          glib-2-56 (LP: #1789476)
        + Many uses of G_GNUC_MALLOC are incorrect
        + Test for BROKEN_IP_MREQ_SOURCE_STRUCT is broken on Windows / Mingw
        + Fix persistent CI failure on glib-2-56
