  I just ran into this. I have the same version of Ruby (installed via rvm) on a Mac OS X Leopard machine.

  Looks like all you can do for now is downgrade to ruby-1.8.7-p174

  Have you tried going to ruby-1.8.7-p249? I just tried:

  ~ [ruby-1.8.7-p249]$ irb -rubygems ruby-1.8.7-p249 > require 'active_support'
  => true ruby-1.8.7-p249 > ActiveSupport::Multibyte::UnicodeDatabase.new.codepoints

  I still see the problem with 1.8.7-p249. What platform are you using, Anthony?

  Denis Odorcic March 25th, 2010 @ 07:31 PM

  I can confirm that I get this problem all the time as well in 1.8.7-p249 and 248. I use the same setups as you guys as well.

  • State changed from “new” to “wontfix”

  Sorry about this, but it's a Ruby issue. Please do raise it on http://redmine.ruby-lang.org/

  • Tag changed from “1.8.7, crash, ruby” to “1.8.7, crash, documentation, ruby”

  Per the original report, it has been reported at ruby-lang: http://redmine.ruby-lang.org/issues/show/2557 .

  I appreciate that it's not something that can be fixed in rails, but given that 3.0 is going to be 1.8.7+ and that AS segfaults on a popular platform for rails development on the current release of 1.8.7, it seems like something you'd want to list in the release notes.

  Jeremy Kemper March 25th, 2010 @ 11:45 PM

  Definitely for the release notes. This is unfortunate :(

  Do you get the same crash on Rails 2.3? On git master?

  Rhett Sutphin March 26th, 2010 @ 03:20 PM

  I had done my testing on master, so yes to that. I just tried 2-3-stable and it segfaults the same way there.

  Jeremy Kemper March 26th, 2010 @ 04:35 PM

  Thanks for verifying, Rhett. Pretty major regression.

  Jeremy Kemper March 26th, 2010 @ 04:37 PM

  Look like all we need is a new 1.8.7 release, since it's fixed in ruby svn already. Whew!

  • Tag changed from “1.8.7, crash, documentation, ruby” to “os x, 1.8.7, crash, documentation, ruby”

  it's fixed in ruby svn already

  Would that it were so. With a just-installed 1.8.7 from SVN HEAD (rvm's 1.8.7-head), I still get the segfault on OS X.

  On the bright side, I finally got around to trying this on something other than OS X. The segfault does not occur on Ubuntu (kernel version 2.6.28-18-server) with 1.8.7-p249. Seems like it is OS X-only.
