QProcess becomes non-responsive with negative return value from Windows console app

I have the following situation. QProcess (either stack or heap) with appropriate finish and error connections made, call start on a Windows console application. If the application returns a non-negative value, everything is okay. If the console application returns a negative value, my spawning application crashes in QProcessPrivate::cleanup() at CloseHandle(pid->hThread) Is this a bug in QProcess, or an misunderstanding of something regarding return values? Thanks.
