PHP segfault on self referencing include

Honestly, I expected this to be somewhat gracefully handled;

justanotherhacker:~$ cat crash.php

<?php

include('crash.php');

?>

justanotherhacker:~$ php crash.php

Segmentation fault

The backtrace is;

justanotherhacker:~$ gdb php

It doesn't appear to be anything more then a potential dos condition to me, but I could be wrong.
