[babel] "Marker does not point anywhere" error?

[babel] "Marker does not point anywhere" error?

Hi

I have the following code block:

#+begin_src sh :session sh
  echo
  ## Copy scripts
  scp SA.sh SA.sub SA.R  Analysis_sensitivity.R
generateLatinHypercubeScenarios.R cluster://export/home/rkrug/sim/nsa/SA/
  # scp SA.sub cluster://export/home/rkrug/sim/nsa/SA/
  # scp SA.R   cluster://export/home/rkrug/sim/nsa/SA/
  ## Copy data
  # scp $ANALYSISDIR/../analysis.db  cluster://export/home/rkrug/sim/nsa/SA/
  echo `date`
#+end_src

When I put my cursor into the block and want to execute it with C-c c I
get usually at the first attempt a "Marker does not point anywhere"
error, and when I, without moving the cursor, do C-c c again, the code
is executed - it is not a serious problem, but a little bit irritating.

Org-mode version 7.5 (release_7.5.113.g9010a)
GNU Emacs 23.2.1 (i686-pc-linux-gnu, GTK+ Version 2.20.1)

Cheers,

Rainer

[Jambunathan K]

Can you do M-x toggle-debug-on-error and copy/paste what comes up in the
backtrace buffer?

[ ... backtrace ... ]

I have a similar behaviour with a gnuplot source block, except that I
get the same error every time I hit C-c C-c. Here is part of the
backtrace:

Debugger entered--Lisp error: (error "Marker does not point anywhere")
  ansi-color-apply-on-region(#<marker in no buffer> #<marker at 217 in *gnuplot*>)
  ansi-color-process-output("")
  run-hook-with-args(ansi-color-process-output "")
  comint-send-input()
  gnuplot-send-string-to-gnuplot(...)
  [... snip ...]

It seems that ansi-color-process-output is the source of trouble. But I
couldn't track it down further. It does not happen every time. I also
don't how to reproduce it for shure.

WinXP
org-mode Org-mode version 7.5 (release_7.5.62.gfb2ac)
GNU Emacs 23.2.1 (i386-mingw-nt5.1.2600) of 2010-05-08 on G41R2F1

Just to be sure: above, it refers to C-c C-c

Here to C-c c... What's the capital "i" you refer to?

Can you explicit which keybinding you're using?

Sorry, I cannot be of much help here.

You can try turning off the below variable and check whether the
situation improves.

,----[ C-h v ansi-color-for-comint-mode RET ]
| ansi-color-for-comint-mode is a variable defined in `ansi-color.el'.
| Its value is t
| 
| Documentation:
| Determines what to do with comint output.
| If nil, do nothing.
| If the symbol `filter', then filter all SGR control sequences.
| If anything else (such as t), then translate SGR control sequences
| into text properties.
| 
| In order for this to have any effect, `ansi-color-process-output' must
| be in `comint-output-filter-functions'.
| 
| This can be used to enable colorized ls --color=yes output
| in shell buffers.  You set this variable by calling one of:
| M-x ansi-color-for-comint-mode-on
| M-x ansi-color-for-comint-mode-off
| M-x ansi-color-for-comint-mode-filter
| 
| You can customize this variable.
| 
| This variable was introduced, or its default value was changed, in
| version 23.2 of Emacs.
