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]:

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

 53) Failure:

 54) Failure:
