# this is a tough one, I think I should explain # Zend use zend_object->properties_table both as zval ** and zval *** # if a zend_object->properties is not initialized, the properties_table is zval ** # while in rebuild_object_properties, zend will store the zval ** to zend_object->properties # then stash the zval ***(ie, zobj->properties_table[0] is zval ** now) to zobj->properties_table[0] # so when a zend_object inherit form multi parent and these parent have a same property_info->offset # properties, will result in a repeat zval **->zval ** transform, which will lead to a segmentfault # *may be* this fix is not the best fix, we should not use this tricky way, and rewrite this mechanism.

Introducing new private variables of the same name in a subclass is ok, and does not lead to any output. That is consitent with normal inheritance handling. (relevant to #60536)
