By uncommenting just one line from the default config you can get to this misconfiguration:
NameVirtualHost *:80 <VirtualHost _default_:443> </VirtualHost> which is not handled properly by the vhost code - httpd serves requests with c->base_server == NULL, httpd -tS segfaults, etc. The check below in vhost.c:remove_unused_name_vhosts seems to be the cause: it stops traversing default_list if it finds any _default_ vhost, so the bogus ipaddr_chain structure further on is never removed; I don't see what this check is for. --- server/vhost.c 11 Mar 2004 19:46:35 -0000 1.85 +++ server/vhost.c 11 Mar 2004 20:34:20 -0000 @@ -500,12 +500,6 @@ ic->sar->virthost, ic->sar->host_port); *pic = ic->next; } - else if (ic->names == NULL) { - /* if server != NULL and names == NULL then we're done - * looking at NameVirtualHosts - */ - break; - } else { pic = &ic->next; } with this applied the bogus ipaddr_chain is found and removed: [Thu Mar 11 20:36:38 2004] [warn] NameVirtualHost *:80 has no VirtualHosts and everything seems to work fine. I'm not really familiar with this code - any comments? joe
