运行rake test:profile时，我得到下面的分段错误。我使用的是ruby 1.9.2p290 (2011-07-09 revision 32553) [i686-linux]。但在Ruby 1.9.2的p320版本中也会发生这种情况，在Ruby 1.9.3中也会出现类似的错误。
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。也可以在帖子末尾看到我的宝石列表。
任何建议都将不胜感激。

1.9.2上的ruby prof存在已知问题。如果由于某种原因，您仍然坚持使用1.9.2，您可以尝试使用wycat的rubby-prof分支，这应该会改善segfault。
