The following code makes apache (?) crash.
<?
$timestamp = 0;
$m = date("m",$timestamp); //$m = 01
$y = date("Y",$timestamp); //$m = 1970
$datestamp = mktime(0,0,0, $m, 0, $y);
?>

I use Apache 2.0.43 under Windows2k SP3.
I have tested against PHP 4.2.3, 4.3.0RC3 and a couple of 4.3.x-dev snapshots from snaps.php.net (from 16-18 dec 2002)
Script doesnt crash if either $m or $y is replaced with a 0 in the mktime() call.

I found this problem after investigating why a certain script crashed, the reason was some data that i've expected to be in the database actually wasn't. In this case i'd expect to get a false back in $datestamp, or some kind of error message.
I've searched the bug database but havent found any similar bug reports.

On Linux 2.4.14, PHP 4.2.3, Apache 1.3.27 i can NOT reproduce this problem.

Last tested with php4-win32-STABLE-200212190930.zip
and the bug still occurs.
Also, Apache says the following in error.log:

Verified on Windows. Crash happens in ext/standard/datetime.c in php_mktime() on line:

t2 = *localtime(&seconds);

This bug has been fixed in CVS.

In case this was a PHP problem, snapshots of the sources are packaged
every three hours; this change will be in the next snapshot. You can
grab the snapshot at http://snaps.php.net/.
 
In case this was a documentation problem, the fix will show up soon at
http://www.php.net/manual/.

In case this was a PHP.net website problem, the change will show
up on the PHP.net site and on the mirror sites in short time.
 
Thank you for the report, and for helping us make PHP better.
