I use XCode 8.2.1 to debug my app. Every time when click the stop debug button, The XCode will crash. This is the following crash info:

Does anyone has the same issue?

Answer 1

There was a race condition bug in lldb that was fixed very recently - should show up in the next official tools release - that could cause debugger shutdown crashes. Without seeing the crashed thread though, it's hard to tell whether it was likely one of these crashes.
