There are certainly still some known instabilities introduced by substring references. You might want to browse the bugs database at http://bugs.perl.org for some other examples.
For what it's worth, the latest bleading-edge perl doesn't have a problem with this testcase, so there's a good chance it'll also be fixed in 5.8.1.
