Fix GH-11972: RecursiveCallbackFilterIterator regression in 8.1.18 When you do an assignment between two zvals (no, not zval*), you copy all fields. This includes the additional u2 data.
Fix GH-11972: RecursiveCallbackFilterIterator regression in 8.1.18 When you do an assignment between two zvals (no, not zval*), you copy all fields. This includes the additional u2 data. So that means for example the Z_NEXT index gets copied, which in some cases can therefore cause a cycle in zend_hash lookups. Instead of doing an assignment, we should be doing a ZVAL_COPY (or ZVAL_COPY_VALUE for non-refcounting cases). This avoids copying u2. Closes GH-12086.
