我用 ruby 1.8.7 有一个很好的时间，我用这个版本的 ruby 和 rails 3.0.x 自从这个版本的 rails 发布。而且我从来没有遇到过分段错误错误。但是现在，在开始使用 rails 3.1.3 开发 ruby 1.8.7 后，当我执行 webrick 并浏览应用程序时，出现以下错误：
/usr/lib/ruby/gems/1.8/gems/rack-1.3.5/lib/rack/utils.rb:380: [BUG] Segmentation fault
ruby 1.8.7 (2010-06-23 patchlevel 299) [i686-linux]
该错误非常不稳定，有时发生在 webrick 的 httputils 上，有时发生在机架上。也许错误与资产管道有某种关系，因为错误发生在这样的一些过程之前：

在调试模式下，该错误不会轻易发生，一行一行。我确实只有一个堆栈跟踪，而且我没有得到超过一次。
此时我禁用了资产管道、coffeescript 和 sass。而且我没有得到更多的错误，但我没有更多的这些功能。
