Subject: Possible hash randomization problems in test suite
Download (untitled) / with headers
text/plain 457b
See http://matrix.cpantesters.org/?dist=BibTeX-Parser%200.66 for a fail/pass overview --- there are many fail reports and almost no pass reports for newer perls. It is not 100% clear, but maybe some hash randomization issue is hitting here. t/13_output.t passes on my smoke machine if I set PERL_HASH_SEED to a special value: env PERL_HASH_SEED=61 PERL_PERTURB_KEYS=NO perl5.23.6 -Mblib t/13_output.t For most other PERL_HASH_SEED values the test fails.

Also, the tests seem to _always_ fail with perl 5.14.4 and 5.16.3. These perls don't have hash randomization implemented, so my guess is that the hash implementation is different here and always returns a different order than expected.
