当我运行rake test:profile时，我得到了下面的分段错误错误。我正在使用ruby 1.9.2p290 (2011-07-09 revision 32553) [i686-linux]。但它也发生在Ruby 1.9.2的p320版本中，并且Ruby 1.9.3也会发生类似的错误。
active_support/testing/performance/ruby.rb:36实际上只是说RubyProf.pause。我正在使用配置文件选项:runs => 5, :metrics => [:cpu_time], :formats => [:tree]运行测试。请看帖子末尾的我的宝石列表。
任何建议都将受到赞赏。

有known issues with ruby-prof on 1.9.2。如果由于某种原因你仍然坚持使用1.9.2，你可以尝试使用wycat's fork of ruby-prof，这应该可以改善段错误。
