Author: Run Paint Run Run
Status: Open, Priority: Normal
Category: core
ruby -v: ruby 1.9.2dev (2009-09-03 trunk 24741) [i686-linux]

$ cat /tmp/thread.rb 
  t = Thread.new do
    begin
      1/0
    rescue ZeroDivisionError
      sleep 3
    end
  end
  
  Thread.pass while t.status and t.status != "sleep"
  t.raise
  t.value
  t.kill

  $ ruby -v /tmp/thread.rb
  ruby 1.9.2dev (2009-09-03 trunk 24741) [i686-linux]
  /tmp/thread.rb:5:in `sleep': unhandled exception
	from /tmp/thread.rb:5:in `rescue in block in <main>'
	from /tmp/thread.rb:2:in `block in <main>'

  $ ruby8 -v /tmp/thread.rb 
  ruby 1.8.8dev (2009-09-04) [i686-linux]
  /tmp/thread.rb:3:in `/': divided by 0 (ZeroDivisionError)
	from /tmp/thread.rb:11:in `value'
	from /tmp/thread.rb:11

On 1.8 Thread#raise re-raises the current exception; on 1.9 it doesn't.
