Up-to-date Valgrind suppression file for GLib/GTK+ ?

[Sébastien Wilmet <swilmet gnome org>]

Hello,

GLib/GTK+ don't seem to provide a Valgrind suppression file upstream. At
the following wiki page:
https://wiki.gnome.org/Valgrind

I see that there is:
1) https://people.gnome.org/~johan/gtk.suppression
2) https://github.com/dtrebbien/GNOME.supp

1) is for Gtk+ 2.12, according to the comment at the top.
2) is more recent, but not up-to-date, for example I see:

==6677== 16 bytes in 1 blocks are possibly lost in loss record 1,488 of 6,253
==6677==    at 0x4C2DA60: calloc (vg_replace_malloc.c:711)
==6677==    by 0x74648FF: g_malloc0 (gmem.c:124)
==6677==    by 0x7464BC7: g_malloc0_n (gmem.c:355)
==6677==    by 0x6DD922B: type_set_qdata_W (gtype.c:3718)
==6677==    by 0x6DD9528: type_add_flags_W (gtype.c:3783)
==6677==    by 0x6DD79C6: g_type_register_fundamental (gtype.c:2659)
==6677==    by 0x6DB59F3: _g_enum_types_init (genums.c:124)
==6677==    by 0x6DDA683: gobject_init (gtype.c:4426)
==6677==    by 0x6DDA6AD: gobject_init_ctor (gtype.c:4487)
==6677==    by 0x400FDA9: call_init.part.0 (in /usr/lib64/ld-2.23.so)
==6677==    by 0x400FEBA: _dl_init (in /usr/lib64/ld-2.23.so)
==6677==    by 0x4000CB9: ??? (in /usr/lib64/ld-2.23.so)

I think all things initialized in gobject_init_ctor() can be suppressed,
the same for other "ctor" functions.

So, is there an up-to-date Valgrind suppression file somewhere? Or is
GNOME.supp the most up-to-date?

I'm aware of:
  "Make GLib valgrind friendly"
  https://bugzilla.gnome.org/show_bug.cgi?id=627423
But in that bug, there is no significant activity since 2013, so if
there is an up-to-date suppression file, it might make sense to include
it upstream, and install it.

Thanks in advance,
Sébastien
