Description:
------------
The attached test script causes a segmentation fault in PHP 5.3.3 and
the current
PHP 5.3 snapshot, presumably because count() is not a defined method in
FooIterator or any of its ancestor classes.
The configure line used to compile the snapshot:
Configure Command => './configure'
'--prefix=/home/matt/Software/php5.3-
201008070030/build/php_build' '--without-pear' '--without-sqlite3'
'--without-
pdo-sqlite' '--without-sqlite' '--enable-debug'
Test script:
---------------
<?php
class FooIterator extends FilterIterator {
public function accept() {
return true;
}
}
$iterator = new FooIterator(new ArrayIterator(array(1)));
echo $iterator->count();
Expected result:
----------------
PHP Fatal error: Call to undefined method FooIterator::count() in
test.php on
line 8
Actual result:
--------------
1Segmentation fault
