           Summary: mod_cgi truncates error replies
           Product: Apache httpd-2
           Version: 2.2.2
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: regression
          Priority: P2
         Component: mod_cgi
        AssignedTo: bugs@httpd.apache.org
        ReportedBy: chip@force-elite.com


A 500 ISE page is not send to clients with mod_cgi, which there is an invalid
CGI.  With mod_cgid the correct output is generated.

To repo:
echo "foo" > foo.cgi

With mod_cgi the output to a client is:
% curl -is --compressed http://example.com/foo.cgi

HTTP/1.1 500 Internal Server Error
Date: Fri, 02 Jun 2006 22:21:49 GMT
Server: Apache/2.2.2 (Unix) mod_ssl/2.2.2 OpenSSL/0.9.7a
Content-Length: 0
Connection: close
Content-Type: text/plain

A zero byte reply. However, just swap the LoadModule to mod_cgid, and restart,
and the reply is this:
HTTP/1.1 500 Internal Server Error

Can we confirm that we don't still suffer from the original
problem?
