-Subject: [PATCH] Revert "[glib/ucdn/icu/ft/ot] Make returned funcs inert"
-
-This reverts commit 5daf3bd4494cce6b4fb074533be9e99c4d9e0edd.
-
-If other atexit callbacks try to destruct the objects we destruct
-in atexit callbacks, bad things will happen.
-
-I'll come up with some other way to catch premature destruction
-of HB-owned objects.
-
-Fixes https://github.com/behdad/harfbuzz/issues/618
