Assertion failure `zend_weakref_unregister(zend_object *, void *, _Bool): Assertion 'tagged_ptr && "Weakref not registered?"' failed`

Description

The following code:

<?php
try {
function garbageCollectionTrigger() {
for ($i = 0; $i < 10000; $i++) {
$obj = new stdClass();
$weakReferences[] = WeakReference::create($obj);
garbageCollectionTrigger();
$root = $document->createElement('root');
$document = new DomDocument();
}
gc_collect_cycles();
}
garbageCollectionTrigger();
} catch (\Throwable $_ffl_e) {}

Resulted in this output:

Start with Zend/zend_weakrefs.c around line 126 and run the supplied test.php command against commit 9dc29aafa5eecc71a9f9e2c7607b588597a91810 using the listed debug and sanitizer configuration. Trace the WeakReference and garbage-collection interactions that reach the assertion, then add or identify a regression test demonstrating that the reproducer no longer aborts.
