PHP Bug Type: Zend Engine 2 problem
Bug description: Segfault in CVS
Description:
------------
I get a segfault with this script:
Reproduce code:
---------------
<?php
class test {
public function start() {
foreach ( $this->array as $foo ) {
$foo->any_method();
}
}
}
$test = new test();
$test->start();
?>
Expected result:
----------------
If $this->array is an array with objects, the method any_method() should
be called on $foo. (works well)
If $this->array is an array with strings, int, ..., php should display an
error. (works well) (Fatal error: Call to a member function any_method()
on a non-object in /var/www/legendz/web/test/test.php5 on line 5 )
If $this->array is an empty array, nothing should happen. (but php
crashes)
Actual result:
--------------
