A typed property of an object properties table is an indirect pointer (IS_IND) to a typed reference (IS_REF).
With https://wiki.php.net/rfc/restrict_globals_usage, php 8.1 arrays are meant to stop containing IS_IND pointers,
and php-src removed code to check for IS_IND pointers.

would also be affected.A more aggressive bug fix would be to also stop allowing references in unserialize entirely, though there's a tiny chance application behavior would depend on these references, so that fix wasn't backported.
