inferior octave freeze and without prompt

inferior octave freeze and without prompt

[Michael Bach]

Hello,

Version info:
Emacs 24.3.1 (from emacsforosx)
Octave 3.8.0 (via homebrew)
on OS X 10.8.5

Problem description:
Being in a buffer with `octave-mode' major mode, M-x `run-octave'
freezes Emacs.  After C-g to get back control and switching to the
inferior octave buffer there is no prompt.  The prompt should read
"octave:1>".  Octave was called with the options:

octave -i --no-line-editing

Steps to reproduce:
1. emacs -Q
2. M-x find-file RET somefile.m
3. M-x octave-mode
4. M-x run-octave
5. C-g
6. M-x switch-to-buffer RET *Inferior Octave*

How to debug this further?  Anyone experiencing the same behaviour?
Please let me know if this ML is not the right place.

Regards,
Michael

Could you grab octave.el from emacs-24 branch
bzr.savannah.gnu.org/emacs/emacs-24/? It should work on 24.3 as well and
possibly also 24.1 and 24.2 (less tested).

We have done some improvements to octave.el and it should work well with
Octave >= 3.8.0. If not please M-x report-emacs-bug.

Cheers,
Leo

I took this as a reason to try out 24.4 - transition was smooth and
Octave interaction works!  Thanks for the push.
