Just to verify this, I tried what I think you meant. My setter now looks like this:
int _ovl_property_set(zend_property_reference *prop_ref, zval *value) {
zend_llist_element *element = prop_ref->elements_list->head;
zval overloaded_property = ((zend_overloaded_element *)(element->data))->element;
zval *tmp;
tmp = value; zval_copy_ctor(tmp); add_property_zval(prop_ref->object, Z_STRVAL(overloaded_property), tmp); return SUCCESS; }
No change.
Nope. Try this instead:
zval *tmp;
ALLOC_ZVAL(tmp); *tmp = *value; zval_copy_ctor(tmp); INIT_PZVAL(tmp);
