Apache dumps when configured as caching proxy

           Summary: Apache dumps when configured as caching proxy
           Product: Apache httpd-2.0
           Version: 2.0.46
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: Critical
          Priority: Other
         Component: mod_proxy
        AssignedTo: bugs@httpd.apache.org
        ReportedBy: sragavan@novell.com


Steps:

1. Configure a Origin server to send documents that will expire in 5 seconds 
(Just to get the problem soon).

ExpiresActive On
ExpiresDefault "now plus 5 seconds"

2. Configure a Proxy server to cache requests.
3. Send a query like 

GET http://164.99.152.95/srini.txt HTTP/1.1
HOST: 164.99.152.95
Connection: Keep-Alive

to the Proxy server, to get srini.txt from Origin server

4. It returns the document from Origin server.Also caches that.


HTTP/1.1 200 OK

Server: Apache/2.0.46 (Win32)
Cache-Control: max-age=5, no-transform

5. Give the Same query again after (10 seconds, allow the cache to become 
stale). The apache dumps core.


The scenario is that it re-validates what is there in the Cache.
I tried it on Netware it abends(Netware core dump). But from the attachment of 
defect #15869, attachment#(id=7167), it happens on unix as well. The scenario 
is also same. It revalidates the cache in that defect also and dumps.

For unix trace, please see the defect#15869, attachment id (id=7168).

I was able to see this on 2.0.45 as well as 2.0.46. Dont know about any 
previous or next release.
