Description:
------------
Related to http://bugs.php.net/bug.php?id=48203
Curl crashes when CURLOPT_STDERR file pointer is closed before calling
curl_exec(), i.e.
$fp = fopen(dirname(__FILE__) . '/bug48203.tmp', 'w');
$ch = curl_init();
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_STDERR, $fp);
curl_setopt($ch, CURLOPT_URL, getenv("PHP_CURL_HTTP_REMOTE_SERVER"));
fclose($fp); // <-- premature close of $fp caused a crash!
curl_exec($ch); // segfault
Error is reproduced on latest svn php5.3, php5.4 and trunk
Fix is also attached here.
