Fixed, on main.
https://git.savannah.gnu.org/cgit/emacs/org-mode.git/commit/?id=deb5ea0fc

There are still some issues with inf-ruby I cannot understand though.
When I tried to evaluate the src blocks multiple times, inf-ruby (AFAIU)
interprets some of the puts output as input for some reason, which is
bizarre and does not look like Org's fault.

May you please check if you can reproduce the same problem on your side?

Instructions:

1. Download the attached bug.org file
2. Clone the latest Org: git clone https://git.savannah.gnu.org/cgit/emacs/org-mode.git
3. cd org-mode
4. make repro REPRO_ARGS="-L /path/to/inf-ruby -l ob-ruby /path/to/bug.org"
5. Go to the second code block (the one with :session)
6. Evaluate it several times
7. At some point, you will see either empty result or an error.
   In the *ruby* buffer, you will see
   _org_babel_ruby_prompt (irb):481:in `<main>': undefined method `_org_babel_ruby_prompt' for main:Object (NoMethodError)
	from /usr/lib64/ruby/gems/3.1.0/gems/irb-1.4.1/exe/irb:11:in `<top (required)>'
	from /usr/bin/irb:25:in `load'
	from /usr/bin/irb:25:in `<main>'
_org_babel_ruby_prompt

# Without a session, this works even when the table isn't shortened:
#
#+begin_src ruby :var raw_data=raw-data :colnames no :exports code :results output
puts(raw_data.count)
#+end_src

#+RESULTS:
: 77


# The next two blocks *only* work when the table is cut off at 73. If the
# last two lines are added back in to the table, the ruby session does not
# return.
# Also, even with a truncated table, I don't get any output without the
# extra call to puts() to print a blank line.
#
#+begin_src ruby :var raw_data=raw-data :session :colnames no :exports code :results output
puts(raw_data.count)
puts()
#+end_src

#+RESULTS:
: 77


#+begin_src ruby :var raw_data=raw-data :session :colnames no :exports code :results value
raw_data.count
#+end_src

#+RESULTS:
: 77
