title: Qt Debugger Console does not see debug sessions
body: <p>Tried asking the official Qt forum first, to no avail.</p>
  
  <p>Qt Creator 4.2.0 (Community), Windows 7 SP1, MSVC 2013 64 bit. Trying to debug a preinstalled example project. Debug session is running, breakpoints work, variable values update, but Debugger Console window keeps saying "Can only evaluate during a debug session" regardless of what I type in it. Any ideas how to fix the thing?</p>
  
  <p>UPDATE: Compile output follows.</p>
