Qt Creator is unable to recover from an infinite loop when debugging

When I start a debugging session in Qt Creator with the code snippet (used for debugging) in the example Qt Creator stops responding and even if I forcefully close the application Qt Creator won't recover. The infinite loop of course is printing out what it should.
In that case I have to manually kill Qt Creator and restart it.
The Visual Studio debugger is able to run and kill the application without a problem.
I use the same Visual C++ 2013 and Windows Kit's compiler/debugger combination in both cases.

The code in the attachment is DirectSound related.
