Bug #10738 Updated: socket functions cause php4 to segmentation fault

ID: 10738 Updated by: sniper Reported By: ngaugler@ngworld.net Old-Status: Open Status: Feedback Bug Type: Reproducible crash Operating system: PHP Version: 4.0.5 Assigned To: Comments: I think the '--enable-debug' didn't get accounted for. Please try deleting config.cache and reconfigure/compile PHP again. Then generate that gdb bactrace. Hopefully it will have more info in it. --Jani Previous Comments: --------------------------------------------------------------------------- [2001-05-08 15:57:51] ngaugler@ngworld.net I recently wanted to do socket based options with PHP4, so I downloaded PHP 4.0.5, compiled it fine. However when I attempted to run the Ex2 Socket Example: Simple TCP/IP client located at http://www.php.net/manual/en/ref.sockets.php PHP 4 core dumped: ./mysocket.cgi X-Powered-By: PHP/4.0.5 Content-type: text/html <h2>TCP/IP Connection</h2> l core Segmentation fault (core dumped) I recompiled PHP4 with the --enable-debug ('./configure' '--with-mysql=/usr/local/mysql' '--with-gd' '--with-zlib' '--with-png' '--with-xml' '--enable-ftp' '--enable-sockets' '--enable-discard-path' '--enable-debug') and analyzed the core: gdb /home/usr/bin/php4 core GNU gdb 19981224 Copyright 1998 Free Software Foundation, Inc.
