Here, fully contained version that will make a 131M leak in 12 lines.
<?php
ini_set("memory_limit", "64M");
function make_arr() {
for($i=0; $i<396768; $i++)
$a[sprintf("%05d",$i)] = array(0 => "PHPLEAKS923889239823", 1
=> "PHPLEAK2349082349898");
return $a;
}
for($i=0;$i<10;$i++)
$zip[$i] = make_arr();
for($i=0;$i<10;$i++)
preg_match("/asdfl/", $zip[$i]["00601"][0]);
?>

It's 8 lines without comments. You want me to write a script to make
the data file instead of just downloading it?
<?php
ini_set("memory_limit", "64M");
$s = file_get_contents("ziplatlong");
$z = unserialize($s);
for($i=0;$i<10;$i++)
$zip[$i] = unserialize($s);
for($i=0;$i<10;$i++)
preg_match("/asdfl/", $zip[$i]["00601"][0]);
?>

Please provide _SHORT_ and complete reproduce script.
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.

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.
