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

Hello,

Running Emacs 24.4, compiled from source I found I cannot kill a buffer when performing these steps:

-          Run emacs -Q

-          Create an org-mode file (i.e. ``myorgfile.org``)

-          Insert the following text:

o   #+BEGIN_SRC C++

#+END_SRC

-          Edit the source block by placing the cursor inside the SRC block.

-          Start C++ mode (c++-mode)

-          Try to kill the buffer.

If you need further information please do not hesitate in contacting me.

Best regards,
Damian.

Please do

M-x toggle-debug-on-error

repeat the problem, and post the resulting backtrace.
(I can't reproduce it.)

Running a manually compiled Emacs 24.4.1 on Debian 
Wheezy(+updates) x86_64, and following the above steps, i can't 
reproduce this either.

From the above description, i assume by the "Start C++ mode" line, 
you're not moving the cursor inside the source block and then 
doing:

   C-c '

(i.e. `org-edit-special`) in order to open a c++-mode buffer for 
editing the block contents?

This should be fixed. Thank you.

However, it is not a good idea to change major mode in an edit buffer,
as it removes local variables used to synchronize with the source block.
Proper major mode, when non-trivial, should be defined with
``org-src-lang-modes' instead.

By the way, here editing should be done by placing the cursor in the org buffer ``myorgfile.org``, and then pressing C-' to edit the source code in a different buffer. And this is the buffer that cannot be killed.

I cannot reproduce this.  I tried both Emacs 24.4 and the pretest of
24.5.  In both cases, Emacs asks me whether to kill a buffer that is
modified, and once I answer YES, the buffer is killed.

Is it possible that you are using Org mode from the Org repository,
not the one bundled with Emacs?

That's weird. Which buffer are you killing, the Org buffer, or the new buffer that is created when pressing C-c ' inside the source block? Is the latter the one I cannot kill.

[Damian Nadales]
I've only installed packages through the emacs package manager, and Org mode was not one of them. The command ``org-version`` reports:

    Org-mode version 8.2.10 (release_8.2.10 @ /home/dnadales/opt/share/emacs/24.4/lisp/org/)

I don't know if there is any other information I could give.

In any case thanks for your time.

There was no "C-c '" in the recipe you posted.

What is the full recipe to reproduce the problem, please?

PMJI, but at <http://permalink.gmane.org/gmane.emacs.orgmode/95159>,
Nicolas Goaziou said "This should be fixed."

Perhaps this bug report can simply be closed then ?

IIUC, he fixed it in:

No, it wasn't. Sorry for that.

I replied to Glenn Morris yesterday, mentioning these extra details.

> What is the full recipe to reproduce the problem, please?
[Damian Nadales]
So the recipe full recipe is:
 - launch emacs -Q
 - Create a buffer ``myorgfile.org``
 - Insert the following text:
   #+BEGIN_SRC C++

  #+END_SRC
- Position the cursor in the source code block (between the BEGIN and END directives)
- Press C-c ' (this will open a new buffer)
- Perform M-x c++-mode in the new buffer
- C-x k (kill the newly created buffer)
- You should see the error message now.

Let me know if there is anything else I could do.

Sorry for the vagueness in my first instructions.

Best regards,
Damian.

Thanks for the fix.

I must add that I discovered the bug by accident. Normally I don't change the mode when editing an special org buffer.

Best,
Damian.
