Bug description: Segfault when calling reflection methods of a dynamic property
Description:
------------
The dynamic properties are introduced in php 5.2 The problem I found was
when you try to call most of the methods of the ReflectionProperty
instance for a dynamic object property, returned with
ReflectionObject::getProperties.
Additionally when you use ReflectionObject:;getProperty($property_name)
for a dynamic property, an exception is thrown! The metter is duscussed in
#37682
Look at the code for more info.
I was able to test only on php 5.2.0! I don't know if the problem still
exists in php 5.2.1!
Reproduce code:
---------------
<?php
$i = new stdClass;
$i->dynamic_member = 'value';
$r = new ReflectionObject($i);
// $r->getProperty('dynamic_member'); throws an exception - there is no
'dynamic_member' property?
$properties = $r->getProperties();
var_dump($properties[0]); // Looks OK
var_dump($properties[0]->getName()); // Also OK
echo $properties[0]->isPublic() ? 'public' : 'notpublic'; // Causes
Segmentation fault
$properties[0]->isPrivate(); // Causes Segmentation fault
$properties[0]->isProtected(); // Causes Segmentation fault
$properties[0]->isStatic(); // Causes Segmentation fault
$properties[0]->isDefault(); // Causes Segmentation fault
$properties[0]->isPrivate(); // Causes Segmentation fault
?>
Expected result:
----------------
object(ReflectionProperty)#3 (2) {
["name"]=>
string(14) "dynamic_member"
["class"]=>
string(8) "stdClass"
}
string(14) "dynamic_member"
public
Actual result:
--------------
object(ReflectionProperty)#3 (2) {
["name"]=>
string(14) "dynamic_member"
["class"]=>
string(8) "stdClass"
}
string(14) "dynamic_member"
Segmentation fault
