I\'m facing same problem described here: why-rails-fails-with-ruby-exe-has-encountered-a-problem-and-needs-to-close. that is ruby get crashed with following error:
... except the installer is now ALSO the crashing 1.9.2-p290
Workaround:
Add (or change)
config.log_level = :warn
in config/environments/development.rb
(not my solution - found it in another thread)
i got the same crashes on windows 7 with 1.9.2-p290. someone said to clear development.log file. i can't believe but after deleting my 12mb development.log everything works fine.
it is possible that a native (C) extension is failing and bringing the whole ruby down; in my case it was sql server adapter looping indefinitely/using whole heap; after we traced and fixed the bug in the adapter (https://github.com/rails-sqlserver/tiny_tds/pull/124) it does not fail again
Running 1.9.2 on windows puts you in a REALLY small minority of users. If you don't have an explicit need for 1.9, I'd use 1.8.7. Specifically, I'd use the package from RailsInstaller: http://railsinstaller.org/
