Thank you for this bug report. To properly diagnose the problem, we
need a backtrace to see what is happening behind the scenes. To
find out how to generate a backtrace, please read
http://bugs.php.net/bugs-generating-backtrace.php
for *NIX and
http://bugs.php.net/bugs-generating-backtrace-win32.php
for Win32

Once you have generated a backtrace, please submit it to this bug
report and change the status back to "Open". Thank you for helping
us make PHP better.

I can not reproduce this. Can you generate a *gdb* backtrace?

i meant FreeBSD 6.0 as said in the header, _not_ 5 as stated in the
body.

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:
--------------
root@dill php5> ktrace httpd -X
pid 30132 (httpd): unaligned access: va=0x11ffc72c pc=0x160a59720
ra=0x160a59e44 op=stq
Segmentation fault
Exit 139
root@dill php5> 

last part of the ktrace:
