Re: bug when 'cd ..' to a directory who's parent has been deleted

[Odd Beck]

Well, in all fareness, this is highly unlikely that it would happen, but it did happen to me while I was cleanup up some rubbish in my filesystem. It wasn't a big deal as I quickly realized what was happening.

Here's the way I reproduced it:

----------------------------------------

Terminal1:
mkdir -p ~/a/b
cd ~/a/b

Terminal2:
cd ~
rm -rf a/

Terminal1:
cd ..
cd: error retrieving current directory..................
----------------------------------------

It might not be a huge issue, but I though I'd report it.

Best regards

The actual filesystem objects still exist, but the named references to them
(pathnames) do not.
