heres a sample script...it seems to crash only when one file includes another file:


--------index.php3------------------
<? include "verify.php3"; ?>
hi

-----------------------------------


--------verify.php3--------------------
<?
if($userdrop_array["disabled"] > 0)
{
echo "hi";
}
?>

------------------------------------------

Same here with apache 1.3.5, Linux 2.0.37 and libc5.
Taking libzend from php4 beta 2 with the latest php4
works.
