[Octave-bug-tracker] [bug #59847] Unexpected behavior of evalin in some cases

[John W. Eaton]

Follow-up Comment #5, bug #59847 (project octave):

Octave currently uses the equivalent of "dbup" to move to the "caller"
workspace.  Since these are related issues, could someone please perform an
additional test using the functions in the attached file?  After unpacking the
tar.gz file, you'll have a directory called dbup-test.  Start Matlab in that
directory and call the function "f3", then follow the displayed instructions
and report the output of all the commands during the session.  Octave shows
the following output:


octave:1> f3
f3var = 3
f2var = 2
f1var = 0
at the debug prompt, execute the commands:

  dbstack
  dbup
  dbstack
  who
  f0

stopped in f1 at line 11
