アボートしました

SEGVを防ぐパッチを添付します。サイズが大きくなっているのは、根本的な対処が必要となったためです。

あとそういえば、ついでに当該の.rbファイルも添付しておきます。

よろしくお願いします。

• Assignee set to tad (Tadashi Saito)

たしかにSEGVします。
ただし、このパッチでは make love に失敗するので愛が足りないようです。

[mame (Yusuke Endoh)]

• Status changed from Assigned to Rejected
• Priority changed from 7 to 3

エイプリルフール終わり。
