PHP 4.0 Bug #6784: Apache 1.3.12 SegFaults at curl_init()

From: msquillace@sogei.it Operating system: RedHat Linux 6.2 2.2.14-12 PHP version: 4.0.2 PHP Bug Type: cURL related Bug description: Apache 1.3.12 SegFaults at curl_init() The following is enough to reproduce the problem: <?php echo curl_version(); /* $ch = curl_init ("http://www.php.net/"); $fp = fopen ("php_homepage.txt", "w"); curl_setopt ($ch, CURLOPT_INFILE, $fp); curl_setopt ($ch, CURLOPT_HEADER, 0); curl_exec ($ch); curl_close ($ch); fclose ($fp); */ ?> As it is, the curl_version is correctly output to the browser, but if you just uncomment the curl_init() line, httpd crashes and in the error_log you see a Segmentation Fault (no data is output to the browser). I get the error with curl 7.2.1, 7.2, 7.1.1, 7.1, and also on a RedHat 6.1 system. I'm using the 'optimized' version of php.ini, but I don't think it is relevant. My PHP 4.0.2 configure line is: ./configure --prefix=/opt/www --mandir=/usr/man \ --with-config-file-path=/opt/www/conf --disable-debug \ --enable-safe-mode --with-exec-dir=/opt/www/php/bin \ --enable-track-vars --enable-magic-quotes \ --with-apxs=/opt/www/bin/apxs --enable-bcmath \ --with-cpdflib=/opt/ClibPDF --with-jpeg-dir=/opt/jpeg \ --with-tiff-dir=/opt/tiff --enable-ftp --with-gd \ --with-mysql=/opt/mysql --with-mm=/opt/mm \ --enable-sysvsem --enable-sysvshm --enable-wddx \ --enable-xml --enable-calendar --with-zlib=/opt/zlib \ --enable-inline-optimization --with-ttf --with-readline \ --with-curl=/opt/curl I've run PHP 4.x with this setup with no problems for the last few months, and simply added the last option a couple of days ago since the curl functions could be very useful for me at work. I can't generate a gdb backtrace right now (after all, I think the problem can be easily reproduced), but if needed I can manage to send it.
