Thanks for submitting the report.  However, more information is
needed.

That ordering is only used if the the locale (selected by LANG or
other) is set to C or POSIX or unset to default to those.  I find that
many people today are setting their locale to use a non-traditional
dictionary sort ordering.  What is your locale?

  locale

Try setting LANG to C or POSIX and repeating the experiment.  Does
that solve the problem?

  export LC_ALL=POSIX

Perhaps your version of 4.0.37 was compiled without support for
locales and your version 4.1 was compiled to support it.  Therefore
one is respecting the locale setting and the other is not?

In any case the character collating sequences are controlled by
strcoll(3) from libc and are dependent upon the behavior there.  Is
the version of libc the same or different in your two test cases?
