Can someone spot why this code
(tested in both 5.2.5 and 5.3)
<?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";
}
?>
outputs:
start 326616
GET 327256
GET 327276
GET 327276
GET 327276
GET 327276

The leak size isn't constant even though my post data size 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.
