Description:
------------
Webserver Segmentation fault using Calendar Application form http://www.k5n.us/webcalendar.php

User with large calendar data is not able to log in anymore. Calendars with less data works fine

This error occurs with PHP version 5.2.9 PHP version 5.2.6 works fine

Both version are compiled on the same machine with following compile options
/configure --with-mysql=/usr/local/mysql --with-openssl  --enable-discard-path --prefix=/usr/local/php5_modul --with-config-file-path=/usr/local/php5_modul/lib --with-apxs2=/usr/local/apache2/bin/apxs --enable-exif --with-iconv --enable-mbstring=all --enable-mbregex --with-zlib --enable-soap --with-gd --with-gettext
 

Actual result:

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 the script requires a 
database to demonstrate the issue, please make sure it creates 
all necessary tables, stored procedures etc.

Please avoid embedding huge scripts into the report.

Unfortunately php is crashing using a calendar application. it can be found at http://www.k5n.us/webcalendar.php .
This application is more or less used as black box.

I can provide access to our system or do some basic debugging if you have an idea what I can do to track down the problem.
