Subject: bug: segfault when using super and method_missing

Hello,

The following code produces a segfault with ruby-1.8.4 from gentoo,  
as well as with ruby-1.8 from cvs and 1.9 from cvs.  There appears to  
be an issue when super is called in the subclass and the parent class  
has method_missing defined.  Strangely, if super is called with  
explicit arguments, no segfault occurs.  Likewise, if the method  
definition in the subclass is modified slightly (see below) the  
segfault is avoided.

Thanks,
Brad

class BaseClass
   def method_missing(*args)
     p args
   end
end

class Article < BaseClass

   # if this is defined as title=(arg) the segfault does not occur
  def title=(*args)
     super(args)  # works
     super(*args) # works
     super        # segfault...
   end
end

a = Article.new
a.body = 'body'
a.title = 'foo'
