#37951 [Com]: Segfaul when using certain curl_setopt option

ID: 37951 Comment by: andrew dot hill at m3 dot net Reported By: headhunter at c-plusplus dot de Status: No Feedback Bug Type: cURL related Operating System: SLES 10.0 - 64 Bit PHP Version: 5.1.4 New Comment: Hi, I have the same issue on a RHEL 4.0 x86_64 machine. The listed example script crashes as described above. I have also copied my MySQL 5.0 libraries from /usr/lib64/mysql to /usr/lib/mysql to allow PHP to compile. In my case I was using PHP 5.0.4, but using the linked PHP 5.2 latest dev release didn't resolve the issue. Any ideas? Thanks!

I'm not very keen to try an development version of PHP on a productive server. What am I buying? ------------------------------------------------------------------------ [2006-06-28 18:24:01] tony2001@php.net Please try using this CVS snapshot: http://snaps.php.net/php5.2-latest.tar.gz For Windows: http://snaps.php.net/win32/php5.2-win32-latest.zip ------------------------------------------------------------------------ [2006-06-28 18:14:47] headhunter at c-plusplus dot de Description: ------------ Hello, I have found a bug which crashes PHP when using CURLOPT_FOLLOWLOCATION. This happens on certain adresses only, the one specified in the example later gives a crash. Example line: curl_setopt ($curl_handle, CURLOPT_FOLLOWLOCATION, 1); // <<< CRASH HERE I don't know my configure line exactly. Anyway, I compiled PHP by hand with--curl and --with-mysql and --with-cli. Rest is as untouched. Unique to my systems where the problems I had getting mysql5 working. It seems there is a bug in the configure Script of PHP which makes it ignore the 64bit Libraries of mysql. I had to copy /usr/lib64/mysql to /usr/lib/mysql to make compiling work. The problem is indenpendant from the php.ini, I tried different one. The default configuration also produces the crash. Reproduce code: --------------- <?php $curl_handle = curl_init(); $timeout = 10; curl_setopt ($curl_handle,CURLOPT_URL, 'www.vipnet.at'); curl_setopt ($curl_handle, CURLOPT_FOLLOWLOCATION, 1); // <<< CRASH HERE $buffer = curl_exec ($curl_handle); print_r ($buffer); ?> Expected result: ---------------- jojo@suse10064lamp:~> php bug.php *** glibc detected *** free(): invalid pointer: 0x00002aaaab7dcb00 *** Aborted Actual result: -------------- jojo@suse10064lamp:~> strace php bug.php [ snip ] open("/dev/tty", O_RDWR|O_NONBLOCK|O_NOCTTY) = 4 writev(4, [{"*** glibc detected *** ", 23}, {"free(): invalid pointer", 23}, {": 0x", 4}, {"00002aaaab7dcb00", 16}, {" ***\n", 5}], 5*** glibc detected *** free(): invalid pointer: 0x00002aaaab7dcb00 *** ) = 71 rt_sigprocmask(SIG_UNBLOCK, [ABRT], NULL, 8) = 0 tgkill(12461, 12461, SIGABRT) = 0 --- SIGABRT (Aborted) @ 0 (0) --- +++ killed by SIGABRT +++ ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=37951&edit=1
