Hello,
The attached org file gives examples of outputs from octave code blocks
that are unexpected and inconsistent.
The attached bug.org file should be opened with
emacs -Q -l init.el bug.org
The problems only occur when the ":session" header is used.

Run with
/usr/bin/emacs -Q -l init.el bug.org
Then execute the code blocks by using C-c C-c in code block.
Unexpected output (as it includes a blank line ": " and "octave >")
#+begin_src octave :session oct1 :results output
x = 1;
x = 1;
x = 1
#+end_src
#+RESULTS:
:
: octave> x = 1
Unexpected output (as it does not include ": x = 1")
#+begin_src octave :session oct2 :results output
x = 1;
x = 1
x = 1;
#+end_src
#+RESULTS:
By comparison, these code block give expected results
#+begin_src octave :session oct3 :results output
x = 1
x = 1
x = 1
#+end_src
#+RESULTS:
: x = 1
: x = 1
: x = 1
#+begin_src octave :session oct4 :results output
x = 1;
x = 1
x = 1
#+end_src
#+RESULTS:
:
: x = 1
: x = 1
Also, if the ":session" headers are removed the all the code blocks give the expected results, for example,
#+begin_src octave :results output
x = 1;
x = 1;
x = 1
#+end_src
#+RESULTS:
: x = 1
