New Comment:
Never mind. The combination of an infinitely growing static array and
some caching in the memory manager made this look like a PHP bug when it
actually wasn't.

Description:
------------
Adding a bug for this so we can track it.
The leak size isn't constant even though the post data size in this
example is constant, and the returned data (a dns error, presumably) is
the same. Seems like there is something weird in our postfield handling
code in the curl extension. Note also that it stabilizes somehow,
although this is an extremely simplified version of a long-running
command-line script that seems to grow on each post with wildly varying
post data.
Reproduce code:
---------------
<?php
function curl($post) {
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "www.fdhfkdsslak.bogus");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
if($post) {
curl_setopt($ch, CURLOPT_POST, 1);
for($args='',$i=0;$i<75;$i++) $args .= "a=$i&";
curl_setopt($ch, CURLOPT_POSTFIELDS, $args);
unset($args);
}
curl_exec($ch);
curl_close($ch);
}
echo "start ".memory_get_usage()."\n";
for($i=0;$i<10;$i++) {
curl(0);
echo "GET ".memory_get_usage()."\n";
}
for($i=0;$i<10;$i++) {
curl(1);
echo "POST ".memory_get_usage()."\n";
}
?>
Expected result:
----------------
No memory_usage increase from one POST request to the next.
Actual result:
--------------
start 326616
GET 327256
GET 327276
GET 327276
GET 327276
GET 327276
