x86_64-linux, sparc-solaris2.10 での make test-all にて、以下のFailureが出ます。

YAML::DBM#shift の rdoc によると、

The order in which values are removed/returned is not guaranteed.
順序が不定であると明記されていますが、テストは特定の順序に依存して書かれているのが原因のようです。
YAML::DBM#to_a, YAML::DBM#values のテストも同様です。（ただしrdocに順序に関する記述は無い。）

49. Failure:
    test_values(Syck::YAMLDBMTest) [/XXX/test/syck/test_yamldbm.rb:169]:
    <["b", "d"]> expected but was
    <["d", "b"]>.

50. Failure:
    test_to_a(Syck::YAMLDBMTest) [/XXX/test/syck/test_yamldbm.rb:51]:
    <[["a", "b"], ["c", "d"]]> expected but was
    <[["c", "d"], ["a", "b"]]>.

51. Failure:
    test_shift(Syck::YAMLDBMTest) [/XXX/test/syck/test_yamldbm.rb:100]:
    <["a", "b"]> expected but was
    <["c", "d"]>.

52. Failure:
    test_values(Psych::YAMLDBMTest) [/XXX/test/psych/test_yamldbm.rb:169]:
    <["b", "d"]> expected but was
    <["d", "b"]>.

53. Failure:
    test_to_a(Psych::YAMLDBMTest) [/XXX/test/psych/test_yamldbm.rb:51]:
    <[["a", "b"], ["c", "d"]]> expected but was
    <[["c", "d"], ["a", "b"]]>.

54. Failure:
    test_shift(Psych::YAMLDBMTest) [/XXX/test/psych/test_yamldbm.rb:100]:
    <["a", "b"]> expected but was
    <["c", "d"]>.

添付のパッチのように返り値をソートするとFailureは消えます。
