httpd.conf
Apache crashes when attempting to rename a top level directory (meaning, the
directory named in the <Directory> directive).
Create a test directory:
# mkdir /tmp/test
# mkdir /tmp/test/foo
# chmod -R a+w /tmp/test
Make the directory visible via httpd by adding a block to the config:
Alias "/foo/bar" "/tmp/test/foo/bar"
<Directory "/tmp/test/foo/bar">
Dav On
Options Indexes
IndexOptions +FancyIndexing
Allow from all
</Directory>
Run httpd -X in a debugger.
Attempt to rename the directory from a client, in this case cadaver:
# cadaver http://localhost:8080/foo/bar
dav:/foo/bar/> mv /foo/bar/ /foo/barf
httpd crashes with this stack trace:

I expect that attempting to rename a directory explicitly named in the
<Directory> block should probably be forbidden.
