QtService on windows will not start as a service for Qt > 5.2.1

When upgrading my Qt libraries to 5.5.1 I found that QtService would not start as a service on Windows, either by using the service Controller methodology (from the QtService example code) or via the Services mmc in control panel. The error code I get is #1053: "The service did not respond to the start or control request in a timely fashion."

The problem seems to happen at the call to pStartService in QtServiceController::start in qtservice_win.cpp

bool QtServiceController::start(const QStringList &args)
{
    Q_D(QtServiceController);
    bool result = false;
    if (!winServiceInit())
        return result;

    // Open the Service Control Manager
    SC_HANDLE hSCM = pOpenSCManager(0, 0, SC_MANAGER_CONNECT);
    if (hSCM) {
        // Try to open the service
        SC_HANDLE hService = pOpenService(hSCM, (wchar_t *)d->serviceName.utf16(), SERVICE_START);
        if (hService) {
            QVector<const wchar_t *> argv(args.size());
            for (int i = 0; i < args.size(); ++i)
                argv[i] = (const wchar_t*)args.at(i).utf16();

            if (pStartService(hService, args.size(), argv.data()))    // <-- This Fails
                result = true;
            pCloseServiceHandle(hService);
        }
        pCloseServiceHandle(hSCM);
    }
    return result;
}

Some things to note:

• The service functionality works as expected for Qt Libraries 4.6.2, 4.8.5, & 5.2.1 on Windows 7 (I have not tested other versions).
• I have no trouble at all on Linux (Qt libraries: 4.6.2, 4.8.5, 5.2.1, 5.4.2, & 5.5.1).
• On Windows, for libraries greater than 5.2.1, I am able to run the service as an application using the -e commandline switch (e.g., C:\> myservice -e "ServiceName")
