Let's back up a moment.  What do you expect the above script to actually
do?  Nothing is the proper and expected behavior -- there is no way for
a child process to change the CWD of the parent so if you are expecting
the CWD to be different after running the script then you have a
misunderstanding of how scripting works.  If you want to affect things
like the CWD or environment of the current process, you can't do it by
invoking a child, you must source the contents of the script in the
current process.
