Today, on the Twitter, @cheesecakeufo users have exposed a bug in the iOS and Mac devices. It is a chaiOS bug. Once the Messages application on the device receives the following link, iPhone/iPad will crash or Respring, and Messages app will be unable to use.
This link points to the GitHub page, causing the Messages application to crash on iOS and Mac devices and causing many other problems. As Messages has the function of preview link, when receiving this message there will be problems, foreign media measured several Respring, and Messages completely stuck.
The only solution currently is to exit the Messages application and then clean up all running tasks to recover.
