rubinius

The following code throws an exception when run with rubinius:

def setcc
  puts "setcc called"
  callcc do|c|
    @c = c
    throw :foo, true
  end
end

result = catch :foo do
  2.times { setcc }
  false
end
@c.call if result

Using MRI 1.8.6, it prints:

setcc called
setcc called

Using rubinius, the result is:

setcc called
setcc called
An exception has occurred:
    Unknown catch label 'foo' (NameError)
