Operating system: FreeBSD 5.3-RELEASE
PHP version: 4.4.6
PHP Bug Type: Session related
Bug description: Apache segmentation fault
Description:
------------
When running some of my php-pages, I get segmentation faults in Apache.
I think I have narrowed it down to session-handling in php, see reproduce
code. Pages not including sessions works fine.
I have upgraded both Apache, PHP and MySQL lately, but don't know if this
is related to the errors I experience.
Systeminfo:
FreeBSD 5.3-RELEASE
Apache 1.3.37
PHP 4.4.6
ZendOptimizer 3.2.2 (disabled for now)
MySQL 4.1.22
register_globals=on
Tests with register_globals=off does not make any difference.
PHP compile options:
./configure --enable-versioning --enable-memory-limit --with-layout=GNU
--with-config-file-scan-dir=/usr/local/etc/php --disable-all
--with-regex=php --with-apxs=/usr/local/sbin/apxs --disable-ipv6
--prefix=/usr/local
Reproduce code:
---------------
<?
session_register("test_sessie");
echo "does this work?";
?>
Expected result:
----------------
Output to screen/browser:
does this work?
Actual result:
--------------
The browser returns a blank page, command line returns "Segmentation fault
(core dumped)".
/var/log/messages:
kernel: pid 459 (httpd), uid 80: exited on signal 11
Apache's error.log:
child pid 458 exit signal Segmentation fault (11)
