 C-c C-c in shell buffer occasionally dumps garbage to the screen
Date: Thu, 16 Apr 2015 11:16:21 -0700

[Message part 1 (text/plain, inline)]

Pressing C-c C-c in a shell mode buffer will occasionally dump garbage
to the screen, and then the bash process dies. I have reproduced this
with 'emacs -Q', but it does not happen every time.

An example of a shell buffer where this happened under 'emacs -Q' is
attached.

I installed Emacs on OS X Yosemite using the following homebrew command:

brew install emacs --with-cocoa --with-glib --with-gnutls \
--with-imagemagick --with-librsvg --HEAD

In GNU Emacs 25.0.50.1 (x86_64-apple-darwin14.1.0, NS appkit-1344.72 Version 10.10.2 (Build 14C1514))

(This bug report unfortunately got no response at the time.)

Very odd -- I can't recall seeing anything like that before.

Are you still seeing this problem in more recent versions of Emacs?

I have not seen this issue recently. (It has been so long I can't remember when I last saw it.) I still use shell-mode frequently, and I have been keeping up to date with the latest stable Emacs releases.

Thanks for following up. This issue can be closed.
