原文摘录

摘自原文(2264 字符中的一小部分)
Using the default `json` library packaged with ruby, one can trigger a segmentation fault by submitting a string with a unicode escape sequence in the range between ` \ud800-\udbff` (https://en.wikipedia.org/wiki/UTF-16#U.2BD800_to_U.2BDFFF).
原文中的代码
require 'json'; JSON.parse('"\ud800"')
