Apache core dumps when reading a certain Virtual Hosts scenario

           Summary: Apache core dumps when reading a certain Virtual Hosts
                    scenario
           Product: Apache httpd-2.0
           Version: 2.0.47
          Platform: Sun
        OS/Version: Solaris
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: Core
        AssignedTo: bugs@httpd.apache.org
        ReportedBy: michael.schroepl@telekurs.com


I have a couple of Virtual hosts, many of them name-based on Port 80, one of
them IP-based on port 443 (using SSL). To give you an impression:

/apache/2.0.47 (root/server) bin/httpd -S
VirtualHost configuration:
wildcard NameVirtualHosts and _default_ servers:
*:443                  ssl.company.de (/usr/local/apache/common2/vh_ssl.conf:1)
*:80                   is a NameVirtualHost
         default server ssl.company.de  (/usr/local/apache/common2/vh_ssl.conf:1)
         port 80 namevhost name1.company.de
(/usr/local/apache/common2/vh_name1.conf:1)
         port 80 namevhost name2.company.de
(/usr/local/apache/common2/vh_name2.conf:1)
         port 80 namevhost name3.company.de
(/usr/local/apache/common2/vh_name3.conf:1)
...
Syntax OK

(names edited, in my case about 30 virtual hosts)

Basically, everything works as expected.

Now I want to have one of my name-based Virtual Hosts the default VH when
entering the machine's IP address and port 80. But when I change one of this
name-based Virtual Hosts from
   <VirtualHost *:80>
to
   <VirtualHost _default_:80>
(like http://httpd.apache.org/docs-2.0/vhosts/examples.html#defaultoneport seems
to tell me) then every execution of "httpd" (starting, stopping, even "httpd
-S") results in a core dump:

bin/apachectl sslstart
[Thu Jul 17 12:51:58 2003] [crit] [Thu Jul 17 12:51:58 2003] file vhost.c, line
232, assertion "rv == APR_SUCCESS" failed
Abort - core dumped

The corresponding source code section is explicitly checking for the "_default_"
value:

    else if (strcasecmp(host, "_default_") == 0
        || strcmp(host, "255.255.255.255") == 0) {
        rv = apr_sockaddr_info_get(&my_addr, "255.255.255.255", APR_INET, port,
0, p);
        ap_assert(rv == APR_SUCCESS); /* must be bug or out of storage */
    }
