Reported By: xenon54 at generationphp dot net
Status: No Feedback
Bug Type: Session related
Operating System: Centos 4.2
PHP Version: 5.1.1
New Comment:
I think I know what the issue is, bad user/passwd login configuration
for the cacti mysql account in include/config.php. When running thru
Apache the error_log will only output "segmentation fault" but if you
run the poller.php script on its own, you'll get the typical error msg
of a failed mysql login (some 10 times?), until it crashs.

Fixed without any reasons.
But still cause segmentation fault with cli.
Will come back if I can reproduce this bug.

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves.
A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external
resources such as databases, etc.
If possible, make the script source available online and provide
an URL to it here. Try to avoid embedding huge scripts into the report.

It was initially on PHP5.1.1.
But the problem persists on PHP5.1.2

Description:
------------
I'm receiving a Segmentation Fault when accessing index.php from cacti.
I recompiled PHP without sessions support and the segmentation fault was
not happening anymore.
httpd-2.0.52-22.ent.centos4
glibc-2.3.4-2.13
cacti-0.8.6h
Thanks for any help
Reproduce code:
---------------
I tried to locate the source of the segmentation fault.
I located the line by using exit; to see where the fault is caused.
To me, it makes no sense but giving it to you anyway.
/cacti/lib/functions.php:137
if (isset($_SESSION["sess_config_array"])) {
$config_array = $_SESSION["sess_config_array"];
}
Expected result:
----------------
Segmentation fault
Actual result:
--------------
