ID: 47285 Comment by: maarten at vivesta dot com Reported By: danger at FreeBSD dot org Status: Assigned Bug Type: Date/time related Operating System: FreeBSD PHP Version: 5.2.8 Assigned To: derick New Comment: Same here. I've added a date_default_timezone_set() before using strtotime() and it removed the error but not the leak. Previous Comments: [2009-02-27 13:53:29] danger at FreeBSD dot org I tried to run my script with php -d error_reporting=E_STRICT test.php and been receiving this error until I stopped the script: Strict Standards: strtotime(): It is not safe to rely on the system's timezone settings. Please use the date.timezone setting, the TZ environment variable or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier.

When I run my test script as this: r...@[temp /var/ports/distfiles/php-5.2.9]# sapi/cli/php /root/test.php No modified php.ini is being used, no additional extensions are being loaded. I can still verify that it leaks. [2009-02-27 11:44:35] der...@php.net I am not forgetting about this, but at the moment just really occupied. Just as a quick question, this is the *stock* PHP without any ports patches, also, if you set the error level to also show e_Strict messages, do you see anything? Also, do you have the date.timezone setting made in PHP.ini?

happen with PHP_5_3.

I can confirm the same leak, running in Apache on Windows. Apache kills
the script after a time limit, but the leaked memory remains leaked;
refreshing the same URL causes the total leaked memory to increase from
there. It looks like it leaks 800KB per second or so, and the script is
killed after leaking about 30MB.
I'm running PHP 5.2.9-2, which came straight from the default Windows
installer.

Applying the patch from oliver at realtsp dot com slowed down the leak,
but did not stop it entirely.

I can confirm that we can reproduce this bug on FreeBSD 7.2 with
php5.2.10 and that the patch provided by bloudon at townnews dot com
does stop the leak.
I had to manually apply the patch because copying out of the html rarely
works, so I have prepared a "clean" vers
