1. Open the project tests\manual\debugger\cli-io\main.cpp from Creator's source repository.
2. In Projects mode, check "Run in Terminal".
3. Make sure that there is no Terminal open, neither in Edit mode nor in Debug mode.
4. Run the program in the debugger.
   No terminal will open up. Opening a Terminal after the execution will not show the program's output.
5. In main.cpp, comment out the first return line.
6. Make sure again that there is no Terminal open, neither in Edit mode nor in Debug mode.
7. Run the program in the debugger.
   Again, no terminal will open up. Opening a Terminal manually will only show the very last line of output: "Enter something:"

The output should not just disappear. If a Terminal is open before debugging the program, this seems to work fine.
