Debugger: LLDB: Stop debugger does not always stop the debugger

Steps to reproduce:

• start debugging any C++ project (doesn't matter if mixed debugging or not)
• when debugger is up and running hit 'Stop' button from the debugger toolbar

Current result:

• app is interrupted (normally at the "return..." line of the main())
• hitting 'Stop' again or 'Continue' leads to closing the app and debugger

Note: if the app is in interrupted state, hitting 'Stop' really stops the app and the debugger. I'd expected the debugger always to stop debugging without standing on the last line of the main() - feel free to correct me or blame lldb...
