柳田です。

make TESTS=-v test-all してみたところ、以下のようになりました。

環境は Windows 2000 SP4 です。

make: *** [test-all] Aborted (core dumped)


Test::Unit::TC_Assertions は test_assertions.rb にありますので、

% make TESTS='-x test_assertions -v' test-all

としたところ、

test_multilevel_collect(Test::Unit::Collector::TestDir): .
test_nil_pattern(Test::Unit::Collector::TestDir): .
test_simple_collect(Test::Unit::Collector::TestDir): .
RUNIT::TestAssert#test_assert_equal_float_0_raise: /var/tmp/ruby_1_8-src/lib/pp.rb:454: [BUG] Segmentation fault
ruby 1.8.4 (2005-12-21) [i386-cygwin]

make: *** [test-all] Aborted (core dumped)

のように、別の場所で SEGV になりました。
(落ち方は同じのようです)

なお、これらのテストを単独で実行した場合は、エラーは起こりませんでした。

また、test_yaml ではエラーは起こりませんでした。

% /var/tmp/ruby_1_8/bin/ruby test/yaml/test_yaml.rb
Loaded suite YAML

さらに、make TESTS=-v test-all を何度か繰り返してみると、
毎回同じところで落ちるというわけではないようです。
ただ、原因はどうやら同一のであるかような雰囲気を受けます。
例を下に挙げます。

なぜこんなところに kernel32.dll が表示されたのかは不明です。
もちろん、ruby のソースディレクトリは kernel32.dll はありません。
(先ほどのメールでは、Windows XP SP2 上で検証しました。
このメールでは Windows 2000 SP4 で検証していますが、
「from .../kernel32.dll」の表示は出ないようです)
