Fixed bug #60536 (Traits Segfault)

# 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.
