----------------------------------------
The following code shows unexpected random object, or segfaults sometimes.

~~~ruby
class << (obj = Object.new)
  src = 1000.times.map {|i|"v#{i} = "}.join("")
  eval("def foo()\n""#{src}nil\n""end")
end

b = obj.method(:foo).to_proc.binding
p b.local_variable_get("v999")
~~~
