I took your advice and rebuilt apache with debugging symbols, and came up with this (following http://httpd.apache.org/dev/debugging.html): root@logsrv:/usr/ports/www/apache13-modssl# gdb httpd (gdb) b ap_process_request Breakpoint 1 at 0x8064944: file http_request.c, line 1311. (gdb) run -X -d /usr/local Starting program: /usr/local/sbin/httpd -X -d /usr/local [Thu Mar 17 12:02:38 2005] [warn] NameVirtualHost *:443 has no VirtualHosts gdb in realloc(): error: junk pointer, too high to make sense Abort (core dumped) If I run 'gdb httpd httpd.core' and then run 'where', I get the following (though I have no idea if it is relavant). Sorry for the long paste: root@logsrv:/usr/ports/www/apache13-modssl# gdb httpd httpd.core warning: exec file is newer than core file. Core was generated by `httpd'.
