Segmentation Fault when running PHP Cli

When I type this in shell (Linux):

php index.php

Sometime PHP script terminate and I get an error saying:

Segmentation Fault

Sometime it work fine and sometime I get an error

In the php script it include PDO (mysql), Curl, some loop and "Simple HTML Dom" library

PHP Version:

username [~/www/]# php -v
PHP 5.2.9 (cli) (built: Oct  9 2010 02:01:46)

How to fix this problem? I had no problem when I tested on Windows 7 (PHP 5.3.0).

It is about a memory access violation. In your case, this error may be due to (non-exhaustive list):

1. a stack overflow (often happens when the recursion level for a given function is too high)

2. too much data to be put in variables (e.g., you try to put the whole content of a huge file in a variable)

To know what causes trouble in your script, try commenting bigger and bigger parts to see which one is at the origin of the bug.

It seems your problem was solved earlier: PHP Out of Memory - Crashes Apache? May be the problem lies in memory leaks of Simple HTML Dom: http://simplehtmldom.sourceforge.net/manual_faq.htm#memory_leak
