      I already created QTBUG-33731 2 years ago. But this issue is closed after certain fixes... but that don't work fully.

      The bug is easy to understand:

      _q_processDied() is called twice

      1) Once by the signal QWinEventNotifier::activated
      This causes cleanup() to be called, and pid to be set to 0

      Later:

      2) QProcessPrivate::waitForFinished
      _q_processDied is called after if (WaitForSingleObject...

      since pid is 0, the crash occurs in QProcessPrivate::findExitCode

      Q_ASSERT(pid) in triggered in debug mode, and in release mode, you crash.

      I looked at 5.6 alpha code, and don't see anything to solve this.
