When I use org-mode emacs to edit a C program, that is, when I edit the segment below:
#+begin_src c #define MAX 100 #+end_src
and after calling the org-edit-src-code function to edit the C code in a new buffer, an error occurs:
Language mode `c-mode 'fails: stringp
and after editing the code in a new buffer, I can neither save nor return to the original buffer.
All other languages can work without any problems, including C ++, elisp, sh.
How can I fix this problem? My version in org-mode is 7.6 and the emacs version is 23.2.
full debugging info (follow the Noufal Ibrahim method):

I am a newbie and I do not know what the problem is. Any tips?
