Suppose the user connects QProcess::readyReadStandardOutput with a slot that calls QCoreApplication::processEvents. Assume the event loop did not handle events between QProcess::start and QProcess::waitForFinished. The process writes to stdout and exits. QProcessPrivate::waitForFinished calls drainOutputPipes which calls QWindowsPipeWriter::waitForReadyRead. This in turn will trigger _q_processDied via the readyRead signal and processEvents. _q_processDied will delete the pid object and set pid to null. After drainOutputPipes returns, _q_processDied is called again but it must not be called if pid is already destroyed. Prevent calling _q_processDied if pid is null.

README
This directory contains autotests and benchmarks based on Qt Test. In order
to run the autotests reliably, you need to configure a desktop to match the
test environment that these tests are written for.
Linux X11:
* The user must be logged in to an active desktop; you can't run the
autotests without a valid DISPLAY that allows X11 connections.
* The tests are run against a KDE3 or KDE4 desktop.
* Window manager uses "click to focus", and not "focus follows mouse". Many
tests move the mouse cursor around and expect this to not affect focus
and activation.
* Disable "click to activate", i.e., when a window is opened, the window
manager should automatically activate it (give it input focus) and not
wait for the user to click the window.
