Current implementation does not make String array.
Please run the following code:

----

def foo
  raise
end

begin
  foo
rescue => e
  # e.backtrace # (X)
  ObjectSpace.each_object(Array){|ary|
    if ary.find{|obj| obj.is_a?(String) and /foo/ =~ obj}
      p ary
    end
  }
end

----

If you run (X), then the code prints out backtrace object.
