PHP 5.2.9-dev (cli) (built: Feb  5 2009 10:52:28)

I also applied distribution patches that come with FreeBSD (exluding
the patch-ext_date_lib_timelib_structs.h one), you may find them at
http://cvsweb.freebsd.org/ports/lang/php5/files.

Verified that the above PHP version still leaks memory, slower but
still.

Description:
------------
The strtotime() function still leaks memory in patched PHP 5.2.8 after
applying patches from http://news.php.net/php.cvs/55000. The memory leak
itself is much smaller than before applying fixes. Before, it took a few
seconds to leak 1gb of mem, now it takes some minutes however it's still
there.

This bug is related to http://bugs.php.net/bug.php?id=46889.

Reproduce code:
---------------
while (true)
{
   $tmp = inc_stamp(time(), 1);
}

function inc_stamp($timestamp, $off_days)
{
   return strtotime("+" . $off_days . " day", $timestamp);
}

Actual result:
--------------
Memory leak reported by top(1). If the script runs for longer time, it
gets killed by kernel since the system is going out of memory and swap.
