httpd version:
-r-xr-xr-x  1 root  wheel  49739 Feb 26 12:51 /usr/libexec/httpd*

>Description:
When requesting a directory without index.html in the following form:
        http://website.org/directory/
it succeeds but
        http://website.org/directory
fails with httpd segfaulting with signal 11!

its incarnation in inetd.conf is:
www             stream  tcp     nowait:600      www:www /usr/libexec/httpd
httpd -H -X -u -M jad text/vnd.sun.j2me.app-descriptor - - -M jnlp
application/x-java-jnlp-file - - -M jar application/java-archive - -
/home/httpd/

Note that it also fails when issued from the command line.

        
>How-To-Repeat:
Configure the native httpd daemon on inetd.conf or start it from the command
line and see it segfaulting in the above example.

        
>Fix:
Looking in a dumped core it turns out to be in the redirect code.
For a workaround, make sure your website allways uses the trailing slash when
refering to directories.
