[BUG] Org-Babel shell problems and crashes with images [9.6.1 (9.6.1-ga6c882 @ /home/joe/.emacs.d/straight/build/org/)]

[Josep Jesus Bigorra Algaba]

Good evening dear community!

This is my first time posting to the mailing list, so I hope I am doing
things right. I am quite new to Emacs and Org but in the short few
months using it, it's been enlightening and amazing.
I have experienced two very crazy bugs lately that are very difficult to
understand and nearly impossible to fix. I am on latest Emacs (from git)
and using the bundled org mode (from git), on openSUSE Tumbleweed,
running with XFCE + Xmonad.

1- Creating a line in an org document that contains more than 2 images
causes Emacs to entirely crash (tested on Emacs 28 all the way to 30),
e.g. [[./dist/example1.png]] [[./dist/example2.png]]
[[./dist/example3.png]]

I am pretty convinced that if you attempt this it will crash on you. I
didn't even have the showing inline images enabled, it doesn't make a
difference.
I have also noticed that having plain links (not surrounded by [[]])
can also lead to crashes sometimes, but difficult to reproduce.

2- Org babel tangle for shell scripts seems to exhibit strange behaviour 
in latest build,
and it adds a strange BOM character at beggining of the script. This
makes it that the script is not runnable anymore. I can
fix this by manually going to exported file and doing a
=set-buffer-file-coding-system RET utf-8= . That seems to remove that
BOM character.

My literate scripts use these options, thought sometimes shebang as
=#!/usr/bin/zsh= :

#+begin_example

#+title: Joe's spin on openSUSE Tumbleweed
#+property: header-args :tangle install :comments org :shebang 
#!/usr/bin/bash
#+auto_tangle: t

#+end_example

Thanks in advance!
I will provide all needed info that additionally is required.

Welcome and thanks for taking the time to send us a message!  I love hearing how much you've enjoyed your experience with Org.  We love it, too!

I'm the ob-shell maintainer, so I'm most interested in your second point, the one related to shell things.

1. Your first point mentions that you've reproduced the bug in Emacs 28 through 30.  Is the same true for this second, shell/tangle related issue?

2. Does the problem happen with both bash and zsh or just zsh? 

3. Can you please give steps to reproduce the problem?

I'm wondering if something like this is enough to reproduce it or if you're doing something different.  (Note that I'm using #!/usr/bin/env zsh instead of #!/usr/bin/zsh because of how my system is set up.)

#+property: header-args :tangle install :comments org :shebang #!/usr/bin/env zsh

#+begin_src emacs-lisp :export no :tangle no
(org-babel-do-load-languages
'org-babel-load-languages
'((shell . t)))  
#+end_src

#+begin_src sh
  readlink /proc/$$/exe
#+end_src

4. Also, are you running into the issue when starting Emacs using `emacs -Q'?

FWIW, I couldn't reproduce it (3,4, 5 times the same png image on one line, displayed or not).

   Org mode version 9.6.1 (release_9.6.1-16-ge37e9b)
   
   GNU Emacs 29.0.60 (build 2, x86_64-pc-linux-gnu, X toolkit, cairo
   version 1.17.6) of 2023-01-24

But, as you managed to crash emacs, you should probably report an
emacs bug about this (M-x report-emacs-bug).
