Instead of running it through your webserver, try the command line...
(with GDB too).

Description:
------------
Using date() in combination with a timestamp makes my httpd segfault on
FreeBSD 5.0/alpha - it worked with PHP 5.0.5 like a charm.
Using just date() with a format string, but w/o a timestamp works w/o
problems.
Reproduce code:
---------------
<?echo date('Y',10000)?>
Expected result:
----------------
it should work?
Actual result:
--------------
