| Subject: | Tests fail with Data::MessagePack 0.50 |
My smokers started to report test fails for Data-MessagePack-Stream-0.07. Test output starts with:
PERL_DL_NONLAZY=1 "/usr/perl5.16.3t/bin/perl5.16.3" "-MExtUtils::Command::MM" "-MTest::Harness" "-e" "undef *Test::Harness::Switches; test_harness(0, 'inc', 'blib/lib', 'blib/arch')" t/*.t
# Failed test 'next ok'
# at t/basic.t line 24.
# Failed test at t/basic.t line 25.
# got: undef
# expected: 'foo'
# Failed test 'next ok'

# Failed test at t/basic.t line 27.
# got: undef
# expected: 'bar'
# Failed test 'next ok'

Statistical analysis suggests that the problem is caused by Data::MessagePack 0.50 (negative theta signifies bad results):
