#42070 [NEW]: Using combined operators on unset values in object's array causes crash
From: michiel at worthit dot nl
Operating system: Windows Vista Business
PHP version: 5.2.3
PHP Bug Type: Reproducible crash
Bug description: Using combined operators on unset values in object's array causes crash
Description:
------------
Using a combined operator on an array within an object causes apache to
crash. Assigning the object's property to a temporary variable ($someArray
= $bar->someArray) and then working with $someArray works as a workaround.
Also this doesn't only apply to just arrays, $foo->bar->value += 1; crashes
apache as well. Furthermore, this behaviour is also witnessed under version
5.2.2 and could not be reproduced on Gentoo Linux 2.6.19.
Reproduce code:
---------------
// Uncomment any lines below to achieve the same result
// $bar = new stdClass();
// $bar->someArray = array();
$bar->someArray[0] += 1;
Expected result:
----------------
$bar to be an object, with the property $someArray to be an array
containing the int value 1 at index 0 :
object(stdClass)#1 (1) {
["someArray"]=>
array(1) {
[0]=>
int(1)
}
}
Actual result:
--------------
Apache crashes, independent of combined operator or index.
