[ruby-dev:21632] SEGV (test_drb.rb)

咳といいます。

CVS版ruby-1.8で試してます。

runitをインストールしてdRubyのtest_drb.rbを実行しましたが、Linux, OSXともに
同じテストでSEGVします。

% ruby18 test_drb.rb
....

Ruby18YieldTest#test_01_one .
Ruby18YieldTest#test_02_two .
Ruby18YieldTest#test_03_many .
Ruby18YieldTest#test_04_many_to_one test_drb.rb:285: [BUG] Segmentation 
fault
ruby 1.8.0 (2003-10-19) [i686-linux]

Aborted

# あ。Ruby18YieldTestのテストはdRubyじゃなくてRubyの挙動のテストだったような…

Linuxでのバックトレースをつけます。
