[debian-users:23466] Segmentation fault on whois

[MATSUDA Yoh-ichi / 松田陽一 <yoh@xxxxxxxxxxxx>]

こんにちは。松田陽一@三鷹です。

[Q]
あるマシンだけ、whois が "Segmentation fault." で異常終了するように
なってしまいました。
ファイルのサイズやタイムスタンプ、ダイナミックリンクされているライブ
ラリファイルも調べてみたのですが、どこも異なっているように見えません。
唯一違うのは、問題のマシン(hoge)がSMP で、他の正常なマシン(fuga)は単
一CPU である位です。

以下に、実行結果を添付します。
他に調べるべき点はありますでしょうか?

# gdb は使ったこともなく、取り敢えず見よう見真似で実行してみましたが、
# 本来の使い方がわかりません。
