日本コントロールシステム(æ ª)の近永と申します。  
よろしくおねがいします。

Ruby で社内サーバアプリケーションを作成し運用していたのですが、  
先日 glibc が 重複した free() の呼び出しを検出した旨のメッセージと  
バックトレース、メモリマップ等が表示されました。  
何度か試していると、以下のメッセージを出す時もありました。  
[BUG] Segmentation fault  
ruby 1.8.5 (2006-08-25) [i686-linux]

この時は Fedora Core のパッケージに含まれていた 1.8.5(2006-08-25)を  
使用していたので、先週公開された 1.8.6-preview1 をビルドして、  
同じアプリケーションを valgrind 経由で起動してみたところ、  
2重 の free() 呼び出しを検出したらしきメッセージを得ました。  
少し長いですが念のため valgrind のログ全部を添付します。  
最後の「Address 0x4E0FF40 is 0 bytes inside a block of size 32 free’d」  
のところがそうだと思うのですが。

再現させるスクリプトですが、この現象が起きるのが起動させて  
まる一日後に落ちる(ことがある)という程度のもので、なかなか小さな  
スクリプトにすることができていません。  
これから探索していくつもりですがかなり時間がかかると思い、
