I use php_curl module, library version 7.10.1
I send around 100 GET requests on one site  for example like this:
<?
for ($i=0;$i<100;$i++) {
  if (!$ch=curl_init()) break;
  curl_setopt($ch,CURLOPT_URL,"http://www.cnn.com");
  error_log("curl start");
  curl_exec($ch);
  error_log("curl end");
}
curl_close($ch);
?>
I use FreeBSD 4.3 and FreeBSD 4.5 with Apache 1.3.26 and php 4.2.3 as apache module.
I included output before curl_exec and after it into php error. On 50-55 times apache thread crashes with message: "child pid 51696 exit signal Segmentation fault (11)." May be memory leak exists deep inside of curl library? Last message in php error log is: "curl start".
I think so, because i used next example where curl handle is only one.
<?
if (!$ch=curl_init()) exit;
for ($i=0;$i<100;$i++) {
  curl_setopt($ch,CURLOPT_URL,"http://www.cnn.com");
  error_log("curl start");
  curl_exec($ch);
  error_log("curl end");
}
curl_close($ch);
?>
The result was same.


Thanks in advance.
