That would be strange.  It does not make sense.

So far so good.

Looks fine.

But then just right at the critical point you did not include enough
information to deduce what is failing. :-( What is the permission at
this point in time of ./myTest?  It appears from the error message
that you do not have permission to run it.  Without that information
it is impossible to say what is happening.  And what was the chmod
command that you ran?
