+Subject: [PATCH] gquark: fix initialization with c++ constructors
+
+C++ constructors may want create new quarks, but we can not guarantee
+that the glib library ctor is executed first. Therefore we make sure
+that quarks are always initialized from g_quark_from_string and
+g_quark_from_static_string
+
+This fixes crashes in glibmm with musl which likely happens on AIX too.
