From:
Operating system: Linux x86-64
PHP version: 5.3SVN-2011-03-17 (SVN)
Package: Reproducible crash
Bug Type: Bug
Bug description:Crash in spl_filesystem_object_get_path
Description:
------------
The attached code crashes on PHP5.3 SVN. Since this is pretty sure only a
null-pointer deref, reporting this as public (non-security related).
Test script:
---------------
<?php
$targetDir =
chr(0).DIRECTORY_SEPARATOR.md5('directoryIterator::getbasename');
$dir = new DirectoryIterator($targetDir.DIRECTORY_SEPARATOR);
while(!$dir->isFile()) {
}
?>
Actual result:
--------------
