To properly diagnose the problem, we need a backtrace to see what is happening behind the scenes. To find out how to generate a backtrace, please read http://bugs.php.net/bugs-generating-backtrace.php for *NIX and http://bugs.php.net/bugs-generating-backtrace-win32.php for Win32 Once you have generated a backtrace, please submit it to this bug report and change the status back to "Open". Thank you for helping us make PHP better. I could not reproduce this crash on debian i386, debian amd64, or SLED 10 i386. Seeking backtrace. ------------------------------------------------------------------------ [2006-08-09 05:49:52] asubstitute at gmail dot com Description: ------------ When I run "php /www/curltest.php" I see a Segmentation Fault. If I put "echo $this->responseData" before the call to curl_close, I see the response data. If I remove the call to curl_close, the script segfaults at the end, due to curl_close being called automatically. cURL was compiled from the newest tarball. This bug exists in the 5.2 snapshot too. php -v : PHP 5.1.4 (cgi-fcgi) (built: Aug 9 2006 00:24:52) Reproduce code: --------------- class curlTest { function __construct($url) { $this->responseData = null; $this->responseError = false; $this->curl = curl_init(); curl_setopt($this->curl, CURLOPT_URL, $url); } function makeRequest() { $this->responseData = curl_exec($this->curl); curl_close($this->curl); } } $interface = new curlTest("http://www.google.com/explanation.html";); $interface->makeRequest(); Expected result: ---------------- Nothing Actual result: -------------- Segmentation Fault ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=38393&edit=1
