Follow-up Comment #15, bug #51388 (project octave):

Philip or Markus - please try the attached oct file. It's a C++ port of
Markus' loop example.

If the oct file returns silently with no messages printed on stderr, then
chdir and getcwd are completely consistent as we expect.

If the m file loop failed to change the directory, then this oct file should
fail as well.

On my system:

>> cwdtest /usr/lib /usr/share
>> ## success

You should be able to pass it either absolute or relative paths.

When I run it under strace here, I can see that the system library functions
chdir and getcwd are called back to back within microseconds of each other and
are always consistent over thousands of test iterations.

(file #41195)
