P1: Critical Description
Application enters the infinite loop.
Valgrind shows no memory errors (leakages).
Call stack (GDB Ubuntu x64):
1 QHashData::allocateNode(int) 0x5d5db8c 2 QQuickParticleDataHeap::insertTimed(QQuickParticleData *, int) 0x1e58b8f8 3 QQuickParticleGroupData::recycle() 0x1e58bd8f 4 QQuickParticleSystem::updateCurrentTime(int) 0x1e58f885 5 QAbstractAnimation::setCurrentTime(int) 0x5ce5b6f 6 QUnifiedTimer::updateAnimationTimers(long long) 0x5ce5e6d 7 QAnimationDriver::advanceAnimation(long long) 0x5ce6a8c 8 QObject::event(QEvent *) 0x5f0a77b 9 QApplicationPrivate::notify_helper(QObject *, QEvent *) 0x4f8d5ec 10 QApplication::notify(QObject *, QEvent *) 0x4f94a17 11 QCoreApplication::notifyInternal2(QObject *, QEvent *) 0x5edf2b8 12 QTimerInfoList::activateTimers() 0x5f3108e 13 ?? 0x5f318a9 14 g_main_context_dispatch 0xaa81197 15 ?? 0xaa813f0 16 g_main_context_iteration 0xaa8149c 17 QEventDispatcherGlib::processEvents(QFlags<QEventLoop::ProcessEventsFlag>) 0x5f31baf 18 QEventLoop::exec(QFlags<QEventLoop::ProcessEventsFlag>) 0x5edd8aa 19 QCoreApplication::exec() 0x5ee6134 20 main main.cpp 24 0x400ee7 ... <More>
In my and test app this infinite loop usually between
QHashData::allocateNode(int) and
QQuickParticleDataHeap::insertTimed(QQuickParticleData *, int)
every n loops 2 more functions are called:
QQuickParticleGroupData::recycle()
QHashData:: detach_helper
So because of this bug I cannot release my applicaion. Because I use particle system for the infinite flows visualisation.
I have reproduced this bug in my app in all OS indicated below. I have written a simple QML app that reproduced this bug. Run it on Win7x64, Ubuntu x 64
It stops responding in about 10hrs.
I believe that if You uncomment setting OPENGL software mode, the app stops responding in 4 hrs.
MAC OS, Win 7 x32, Win7 x64, Ubuntu x64
