Hi there everyone, I have had a stable dev environment for some time now, well until my laptop was stolen ☹ I am in the process of getting everything set-up again but I am facing a problem with the Ruby interpreter. I am using 1.8.6 patch level 111, I switched back from MySQL 5.1 to a 5.0 version, I have the MySQL gem 2.8.1 installed with Rails 2.3.4. When running any Rails app, have so far just used it with Mongrel as the server, I get the following error: C:/Ruby/lib/ruby/gems/1.8/gems/activesupport-2.3.4/lib/active\_support/ multibyte/chars.rb:158: [BUG] Segmentation fault ruby 1.8.6 (2007-09-24) [i386-mswin32] This application has requested the Runtime to terminate it in an unusual way. Please contact the application’s support team for more information. Any ideas on how I can go about resolving this? I am in the process of getting VirualBox so I can run Ubuntu in there and use it for all my Ruby/Rails development but, I would love to have this issue on Windows resolved in the mean time. Thank you, Schalk ---

Hi all, I completely removed MySQL 5.1, reconfigured the 5.0 instance and the copied the libmysql.dll to ruby/bin and everything is working! Schalk
