And I seem to believe that it worked too, that is, shell mode was able to track the directory change. By the way, is it correct ot report here bugs found in the CVS version, without a patch, or should I write to emacs-pretest-bug@gnu.org instead, as the report-emacs-bug command would do? _______________________________________________ Emacs-devel mailing list Emacs-devel@gnu.org http://mail.gnu.org/mailman/listinfo/emacs-devel ^ permalink raw reply [flat|nested] 8+ messages in thread

I don't think it makes much difference. 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 GNU Emacs 21.2.50.2 (i686-pc-linux-gnu, X toolkit, Xaw3d scroll bars) of 2002-03-20 on pot.cnuce.cnr.it I am updating from the latest sources before investigating that. _______________________________________________ Emacs-devel mailing list Emacs-devel@gnu.org http://mail.gnu.org/mailman/listinfo/emacs-devel ^ permalink raw reply [flat|nested] 8+ messages in thread
