原文摘录

摘自原文(985 字符中的一小部分)
Sorry I was not quite sure about the scope. This bug is not triggerable in the sandbox, because it does not use the Random class, but it is triggerable in mruby with the following piece of code:
原文中的代码
$r = Random.new
a = Object.new
def a.to_int
    $r.rand
end

$r.initialize a
