Previous Comments: ------------------------------------------------------------------------ [2003-11-21 21:28:17] magnus@php.net What MPM module are you using ? worker, prefork, other ? ------------------------------------------------------------------------ [2003-11-21 21:27:56] sniper@php.net 1. Use the bundled GD library (just plain --with-gd) 2. Try ./configure --help to see what configure options exist and what they actually do.. For example, you don't need --enable-sigchild (known to cause problems) And only use either Freetype 1 OR 2. Not both. (remove --with-ttf) ------------------------------------------------------------------------ [2003-11-21 13:48:25] james at vcv dot net Thank you for your help. I have tried to generate backtrace using various methods: HTTPD -X, (gdb) run -X, and php_cli but failed to get any result except what I provided in the first report 'Couldn't get registers: Operation not permitted.' I upgraded gdb to latest version 6. It did not help. Somewhere I read that I need to upgrade the kernel for it to work. My current kernel is 2.4.20-8 Apache model: httpd-2.0.48 ./configure --prefix=/usr/local/apache_ssl \ --enable-modules="vhost_alias" \ --enable-ssl \ --with-ssl=/usr/local/openssl \ --enable-so ------------------------------------------------------------------------ [2003-11-21 11:57:54] iliaa@php.net Please generate a backtrace of the crash.
