One example that got introduced when Qt Quick2 was imported into the
qtbase repository.
operator new(unsigned int) (vg_replace_malloc.c:255)
QUnifiedTimer::instance(bool) (qabstractanimation.cpp:183)
QAnimationDriver::~QAnimationDriver() (qabstractanimation.cpp:461)
QDefaultAnimationDriver::~QDefaultAnimationDriver()
QUnifiedTimer::~QUnifiedTimer()
QUnifiedTimer::~QUnifiedTimer() (qabstractanimation_p.h:146)
void qThreadStorage_deleteData<QUnifiedTimer>(void*, QUnifiedTimer**)
QThreadStorage<QUnifiedTimer*>::deleteData(void*) (qthreadstorage.h:140)
QThreadStorageData::finish(void**) (qthreadstorage.cpp:203)
QCoreApplicationPrivate::cleanupThreadData() (qcoreapplication.cpp:377)
QGuiApplicationPrivate::~QGuiApplicationPrivate() (qguiap....cpp:406)
QApplicationPrivate::~QApplicationPrivate() (qapplication.cpp:208)
QApplicationPrivate::~QApplicationPrivate() (qapplication.cpp:212)
QScopedPointerDeleter<QObjectData>::cleanup(QObjectData*)
...
the easiest fix would be:
QAnimationDriver::~QAnimationDriver()
{
- QUnifiedTimer *timer = QUnifiedTimer::instance(true);
- if (timer->canUninstallAnimationDriver(this))
+ QUnifiedTimer *timer = QUnifiedTimer::instance(false);
+ if (time && timer->canUninstallAnimationDriver(this))
uninstall();
}
ask the 'factory' to not create an instance. I could only trace this
code back to import of Qt Quick2 (anyone has nice git grafts?). Can
we get a 'clean' shutdown into the goals of Qt5, even if it is only
done in a debug build?
cheers
