The setcookie() cause a GPF then I call it with the cookie data returned from serialize() with more than 5 or 6 elements in array... 

This code crash the PHP 3.14 in Win95 and don't produce any result in WinNT, except for a php.exe zumbie... 

<?
$y=array("1","2","3","4","5","6","7","8");
$x=serialize($y);
setcookie("teste",$x,time()+3600);
?>

I get php 3.14 binary  from normal mirror from php.net

I put the code directly in php, no by a web server, and the result is the same.

Configuration:
Win95b pentium 166 32mb
WinNT+SP6 96MB

PS. I try this in php 3.13 also, and the problem have too.
