Xinchen Hui 707f658c33 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.

--TEST--
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)
--FILE--
<?php
error_reporting(E_ALL | E_STRICT);
class Base {
protected $hello;
}
trait THello1 {
protected $hello;
}
// Protected and public are handle more strict with a warning then what is
// expected from normal inheritance since they can have easier coliding semantics
echo "PRE-CLASS-GUARD\n";
class SameNameInSubClassProducesNotice extends Base {
use THello1;
}
echo "POST-CLASS-GUARD\n";
// now the same with a class that defines the property itself, too.
class Notice extends Base {
use THello1;
protected $hello;
}
echo "POST-CLASS-GUARD2\n";
?>
--EXPECTF--
PRE-CLASS-GUARD
Strict Standards: Base and THello1 define the same property ($hello) in the composition of SameNameInSubClassProducesNotice. This might be incompatible, to improve maintainability consider using accessor methods in traits instead. Class was composed in %s on line %d
POST-CLASS-GUARD
Strict Standards: Notice and THello1 define the same property ($hello) in the composition of Notice. This might be incompatible, to improve maintainability consider using accessor methods in traits instead. Class was composed in %s on line %d
POST-CLASS-GUARD2
