It's not clear what you expect to happen.

I'm not sure how you managed to remove the parent directory, since rmdir
doesn't generally allow you to remove a directory that's not empty, but
let's assume that you're in an orphaned directory (one without a parent).

`cd ..' should fail, since the parent no longer exists, and the pathname
canonicalization should fail, since there's presumably no longer a valid
path to reach the current directory.  No value for $PWD is correct.
