<?php 
include ("http://www.server.com/index.html");
?>
--with-apache=../apache_1.3.12 --with-config-file=/usr/local/etc/php4 --with-exec-dir=/usr/local/bin/php4 --enable-track-vars --disable-debug --disable-short-tags --with-gdbm --with-imap --with-mcrypt --with-mhash --with-mysql --with-xml --with-zlib

it crashes with/without zend debug, with 1.3.14 and 1.3.12 apache server. on turbolinux server this works ok, crashes just on debian with the same compile time settings etc.

Could you please add a sample script which causes 
this crash into this bug report?
It propably isn't the include/require which crashes
but something which you have in the included files.

Okay, I tried to include the same page you did, and it
worked just fine. Have you tried PHP 4.0.4 ?
Does it work any better?

Have you tried latest snapshots from http://snaps.php.net/
as I'm using latest CVS myself and it works.

User feedback:
--------------

Currently I have not time for such experiments.
I should note that at least on Sparc with the same
configuration and operating system everything works 
ok.

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

Suspended until bug reporter has time to test 
fixes..
