QThread crashes on exit

[mhoover]

QThread attempts to lock something when it exits using a QMutexLocker class.

void QThread::exit(int returnCode)
{
    Q_D(QThread);
    QMutexLocker locker(&d->mutex);   // <------ Crashes here! d == 0x0
    d->data->quitNow = true;
    for (int i = 0; i < d->data->eventLoops.size(); ++i) {
        QEventLoop *eventLoop = d->data->eventLoops.at(i);
        eventLoop->exit(returnCode);
    }
}

void QThread::exit(int returnCode)
{
    Q_D(QThread);
    QMutexLocker locker(&d->mutex);   // <------ Crashes here! d == 0x0
    d->data->quitNow = true;
    for (int i = 0; i < d->data->eventLoops.size(); ++i) {
        QEventLoop *eventLoop = d->data->eventLoops.at(i);
        eventLoop->exit(returnCode);
    }
}

Just trying to declare the QMutexLocker causes a crash.

This looks like a Qt bug, but I'm not sure.

Any ideas? It looks like "d" might not have been allocated.
