Bug #17782 Updated: Apache2 crashes on curl_exec()

ID: 17782 Updated by: kja@filanet.dk Reported By: erik@nflare.com Status: Open Bug Type: Apache2 related Operating System: WinXP PHP Version: 4.2.1 New Comment: I have seen the same on Win2000. With the example from the documentation <?php $ch = curl_init ("http://www.example.com/"); $fp = fopen ("example_homepage.txt", "w"); curl_setopt ($ch, CURLOPT_FILE, $fp); curl_setopt ($ch, CURLOPT_HEADER, 0); curl_exec ($ch); curl_close ($ch); fclose ($fp); ?> it crashes (application error/GPF) with PHP 4.2.1 both when run from commandline and as module under Apache 1.3.24 It works fine with PHP 4.1.2. If removing the line curl_setopt ($ch, CURLOPT_FILE, $fp); it works fine with PHP 4.2.1 but that is of course a totally different behavior. Seems to be a CURL bug ... I have not invested time in figuring out how to do a backtrace on Win32. I hope above should be sufficiently detailed to track down the issue. Previous Comments: ------------------------------------------------------------------------ [2002-06-16 17:21:52] cynic@php.net you will need to buy (or find a free one) a compiler, and a debugger. the only supported by the PHP team (to my knowledge) is the MS Visual Studio. for advice on getting a backtrace from that consult the product's documentation. ------------------------------------------------------------------------ [2002-06-16 17:15:11] erik@nflare.com Derick, I went to that page, but I couldn't find any information on how to run the backtrace in Windows. Looked like all unix commands to me. Could you please help me? Thanks. ------------------------------------------------------------------------ [2002-06-16 09:46:41] derick@php.net Thank you for this bug report. 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 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. ------------------------------------------------------------------------ [2002-06-16 09:09:27] erik@nflare.com Heres the error.log entry for the crash: [Sun Jun 16 09:07:20 2002] [notice] Parent: child process exited with status 3221225477 -- Restarting. [Sun Jun 16 09:07:21 2002] [notice] Parent: Created child process 2692 [Sun Jun 16 09:07:21 2002] [notice] Child 2692: Child process is running [Sun Jun 16 09:07:22 2002] [notice] Child 2692: Acquired the start mutex.

And that statement is this one: curl_exec ($ch); Whenever I run this script it says Apache2 has encountered an error and needs to be closed, but the ie windows doesnt close, and the Apache2 server is still running. Maybe thats WinXP handling an error quietly or something. The example_homepage.txt is still blank. I enabled ctype, curl, gd2, ming, printer, and zlib. I thank you for your time. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=17782&edit=1
