Can anyone else replicate this change of behavior?
Yes. I could reproduce that on an Archlinux box after updating to perl 1.8.0. hamster might also fail with the same error, I just updated its perl from 1.6.3 to 1.8.0.
Is there anything about it in the Perl release notes?
Just by having a look at the release notes of Perl, there are still nothing describing changes between 1.6.3 and 1.8.0:
It looks quite a bit like somebody's fixed a line-counting bug inside Perl, which may mean that we'll have to maintain two expected-output files or else remove these particular test cases. Which would be annoying.
