From: [EMAIL PROTECTED] Operating system: Ubuntu PHP version: 5.3.0alpha2 PHP Bug Type: cURL related Bug description: curl enabled PHP segfaulting with OpenSSL
Description: ------------ This segfault only exists when PHP is compiled with Curl support. However, Curl is not being called when generating the segfault. Also, this happens only when libcurl has OpenSSL support but no segfault exists with GnuTLS support. The following bug is heavily related: http://bugs.php.net/bug.php?id=40926 But it's labeled as pgsql centric, so this is an attempt to make this a known Curl + OpenSSL bug. Please feel free to relabel these bugs where they belong. The configure line is: ./configure --enable-debug --with-curl --with-apxs2=/usr/bin/apxs2 --prefix=/home/user/php Curl information: cURL Information => libcurl/7.18.0 OpenSSL/0.9.8g zlib/1.2.3.3 libidn/1.1 And for good measure, when Curl is compiled against the following there is no segfault: cURL Information => libcurl/7.18.0 GnuTLS/2.0.4 zlib/1.2.3.3 libidn/1.1 Reproduce code: --------------- The exact code, in this case, is a simple svn call: <?php $url = 'http://phpminadmin.svn.sourceforge.net/svnroot/phpminadmin/trunk/index.php'; $blame = svn_blame($url); print_r($blame); Expected result: ---------------- No segfault Actual result: -------------- The code "works", but the core is dumped with the following backtrace: (gdb) bt #0 0xb73f7fb0 in ??
