From: Charles Nutter Date: 2011-01-12T14:10:04+09:00 Subject: [ruby-core:34405] [Ruby 1.9-Bug#4251] Segmentation fault when using ruby-prof and Ruby 1.9.2 Issue #4251 has been updated by Charles Nutter. It's certainly not a perfect 1.9 implementation, but profiling on JRuby's 1.9 mode using --profile or --profile.graph (or the jruby-prof gem) may also be a fine stand-in for now. The profiling boundaries are similar to ruby-prof, and may reveal the same bottlenecks as running under Ruby 1.9. Of course, there are other challenges to "just run it" on JRuby... ---------------------------------------- http://redmine.ruby-lang.org/issues/show/4251 ---------------------------------------- http://redmine.ruby-lang.org
