# 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.

Bug #60536 (Traits Segfault)
|
|
--FILE--
|
|
<?php
|
|
trait T { private $x = 0; }
|
|
class X {
|
|
use T;
|
|
}
|
|
class Y extends X {
|
|
use T;
|
|
function x() {
|
|
return ++$this->x;
|
|
}

}

class Z extends Y {

|
function z() {

|
return ++$this->x;

}
|
|
}
|
|
$a = new Z();
|
|
$a->x();

echo "DONE";

Strict Standards: X and T define the same property ($x) in the composition of Y. This might be incompatible, to improve maintainability consider using accessor methods in traits instead. Class was composed in %sbug60536_001.php on line %d
