Bug description: memory_limit doesn't word
Description:
------------
php compiled with --enable-memory-limit, but setting the value of
memory_limit more then certain number won't affect scripts.
tried set the value of memory_limit in both php.ini and script body -
nothing helped.
Reproduce code:
---------------
<?php
echo ini_get('memory_limit'),"\n";
ini_set('memory_limit', 100000000);
echo ini_get('memory_limit'),"\n";
ini_set('display_errors', 1);
ini_set('error_reporting', E_ALL);
function a()
{
echo 'fck oyu!';
}
register_shutdown_function('a');
$zz = 'u';
for($i=1; $i<1000; $i++)
{
$zz .= $zz;
echo $i,' - ', memory_get_usage(),"<br>\n";flush();
}
?>
Expected result:
----------------
allocate at least 100MB of memory and die if exceeded.
Actual result:
--------------
100M
100000000
