[kinfocenter] [Bug 414200] Info Center crashes on exit
https://bugs.kde.org/show_bug.cgi?id=414200 Harald Sitter changed: What|Removed |Added Resolution|--- |DUPLICATE CC||sit...@kde.org Status|REPORTED|RESOLVED --- Comment #14 from Harald Sitter --- This is almost certainly a side effect of bug 413003. When kinfocenter doesn't crash because you opened the energy info twice, it would crash on exit when solid tries to clean up its internal pointers only to find that some were deleted already. There are no other modules using solid in the way energy does, so it's a fairly safe bet that this is a duplicate of 413003. *** This bug has been marked as a duplicate of bug 413003 *** -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=414200 --- Comment #3 from Matt Fagnani --- Created attachment 124237 --> https://bugs.kde.org/attachment.cgi?id=124237&action=edit valgrind log from kinfocenter run when clicking Energy Information then closing I ran valgrind --log-file=valgrind-kinfocenter-energy-close-2.txt --track-origins=yes kinfocenter & I reproduced the crash in the same way as in my previous comment. The valgrind log showed an invalid read in wl_proxy_unref at wayland-client.c:229 and an invalid write in wl_proxy_unref at wayland-client.c:230 in libwayland-client. They appeared to be use-after-free errors like those I've previously reported for kwin_wayland, plasmashell, konsole, powerdevil, etc. ( https://bugs.kde.org/show_bug.cgi?id=409688 ) Several Conditional jump or move depends on uninitialised value(s) messages were shown. An invalid read in Solid::DevicePrivate::~DevicePrivate() at device.cpp:222 occurred within freed memory. An invalid read at the address 0x8 in data at qpointer.h:86 was like the trace of the crashing thread. The use-after-free error in Solid::DevicePrivate::~DevicePrivate() might have led to the invalid pointer being used with the segmentation fault as a result. ==3962== Invalid read of size 8 ==3962==at 0x1801AE84: Solid::DevicePrivate::~DevicePrivate() (device.cpp:222) ==3962==by 0x1801AFFC: Solid::DevicePrivate::~DevicePrivate() (device.cpp:225) ==3962==by 0x1801C606: Solid::DeviceManagerPrivate::~DeviceManagerPrivate() (devicemanager.cpp:58) ==3962==by 0x1801E27C: Solid::DeviceManagerPrivate::~DeviceManagerPrivate() (devicemanager.cpp:63) ==3962==by 0x5AFC390: QThreadStorageData::finish(void**) (qthreadstorage.cpp:200) ==3962==by 0x5CA1500: QCoreApplicationPrivate::cleanupThreadData() (qcoreapplication.cpp:520) ==3962==by 0x560E7B4: QGuiApplicationPrivate::~QGuiApplicationPrivate() (qguiapplication.cpp:1611) ==3962==by 0x4FCC3BC: QApplicationPrivate::~QApplicationPrivate() (qapplication.cpp:181) ==3962==by 0x5CD0D46: cleanup (qscopedpointer.h:60) ==3962==by 0x5CD0D46: ~QScopedPointer (qscopedpointer.h:107) ==3962==by 0x5CD0D46: QObject::~QObject() (qobject.cpp:891) ==3962==by 0x5CA113D: QCoreApplication::~QCoreApplication() (qcoreapplication.cpp:892) ==3962==by 0x560EE20: QGuiApplication::~QGuiApplication() (qguiapplication.cpp:649) ==3962==by 0x4FCE50D: QApplication::~QApplication() (qapplication.cpp:773) ==3962== Address 0x1a7bd5d0 is 16 bytes inside a block of size 24 free'd ==3962==at 0x483AEFC: operator delete(void*) (vg_replace_malloc.c:586) ==3962==by 0x6903688: QV4::MemoryManager::sweep(bool, void (*)(char const*)) (qv4mm.cpp:926) ==3962==by 0x6903708: QV4::MemoryManager::~MemoryManager() (qv4mm.cpp:1173) ==3962==by 0x6A89059: QV4::ExecutionEngine::~ExecutionEngine() (qv4engine.cpp:659) ==3962==by 0x6987517: QJSEngine::~QJSEngine() (qjsengine.cpp:379) ==3962==by 0x6AC7F39: QQmlEngine::~QQmlEngine() (qqmlengine.cpp:1072) ==3962==by 0x635A94A: _M_release (shared_ptr_base.h:155) ==3962==by 0x635A94A: _M_release (shared_ptr_base.h:148) ==3962==by 0x635A94A: ~__shared_count (shared_ptr_base.h:730) ==3962==by 0x635A94A: ~__shared_ptr (shared_ptr_base.h:1169) ==3962==by 0x635A94A: ~shared_ptr (shared_ptr.h:103) ==3962==by 0x635A94A: ~QmlObjectSharedEnginePrivate (qmlobjectsharedengine.cpp:41) ==3962==by 0x635A94A: operator() (unique_ptr.h:81) ==3962==by 0x635A94A: ~unique_ptr (unique_ptr.h:284) ==3962==by 0x635A94A: KDeclarative::QmlObjectSharedEngine::~QmlObjectSharedEngine() (qmlobjectsharedengine.cpp:74) ==3962==by 0x635AA7C: KDeclarative::QmlObjectSharedEngine::~QmlObjectSharedEngine() (qmlobjectsharedengine.cpp:76) ==3962==by 0x5CCFDAB: QObjectPrivate::deleteChildren() (qobject.cpp:2016) ==3962==by 0x500BD58: QWidget::~QWidget() (qwidget.cpp:1696) ==3962==by 0x4A93BE5: KCModule::~KCModule() (in /usr/lib64/libKF5ConfigWidgets.so.5.64.0) ==3962==by 0x488C92C: KCModuleQml::~KCModuleQml() (kcmoduleqml.cpp:208) ==3962== Block was alloc'd at ==3962==at 0x4839E86: operator new(unsigned long) (vg_replace_malloc.c:344) ==3962==by 0x1801B4DB: Solid::Device::asDeviceInterface(Solid::DeviceInterface::Type const&) const (device.cpp:189) ==3962==by 0x2877DACE: as (device.h:232) ==3962==by 0x2877DACE: BatteryModel::data(QModelIndex const&, int) const (batterymodel.cpp:75) ==3962==by 0x68F874A: data (qabstractitemmodel.h:458) ==3962==by 0x68F874A: value (qqmladaptormodel.cpp:414) ==3962==by 0x68F874A: QQmlDMCachedModelData::metaCall(QMetaObject::Call, int, void**) (qqmladaptormodel.cpp:282) ==3962==by 0x6A0A043: readProperty (qqmlpropertycache_p.h:328) ==3962==by 0x6A0A043: loadProperty(QV4::ExecutionEngine*, QObject*, QQmlPropertyData const&) (qv4qobjectwrapper.cpp:178) ==3962==by 0x6A0BB3B: QV4::QObjectWrapper::virtualResolveLookupGetter(QV4::Object const*, QV4::ExecutionEngine*, QV4::Look

I started kinfocenter. I clicked Energy Information. I closed kinfocenter. Dr. Konqi showed a segmentation fault in QPointer::data (this=0x28) at /usr/include/qt5/QtCore/qpointer.h:85.
