Re: cd - in shell buffers does not work any more

[Francesco Potorti`]

       If I type `cd -' in a shell buffer I get an error:
   
       cd: No such directory found via CDPATH environment variable
   
   Tht is very strange, since it seems to be an error from the shell.  (I
   don't know what `cd -' is supposed to do.)
   
cd - swaps the two top entries in the cd history stack of the shell.
Basically, it brings you to the dir where you have last been.

Anyway, it is true that it is a strange error.  For that emacs, I can
reliably make it crash really simply with shell.el:

emacs -q
M-x shell RET
C-d              --> signal 11

I am updating from the latest sources before investigating that.
