--- Comment #24 from Matt Fagnani <matthew.fagn...@utoronto.ca> --- Created attachment 138403 --> https://bugs.kde.org/attachment.cgi?id=138403&action=edit New crash information added by DrKonqi systemsettings5 (5.21.5) using Qt 5.15.2 - What I was doing when the application crashed: I tried to reproduce the System Settings crash in #429027 by selecting all the items from Startup and Shutdown down to Regional Settings in the sidebar menu on the left quickly so that sometimes the kcm screens didn't load before I selected the next one. I was using Plasma 5.21.5 on Wayland with KF 5.81.0 and Qt 5.15.2 in a Fedora 34 KDE Plasma installation. System Settings segmentation faulted in std::__atomic_base<QObjectPrivate::SignalVector*>::store(QObjectPrivate::SignalVector*, std::memory_order) at /usr/include/c++/11/bits/atomic_base.h:811 in libstdc++-devel-11.1.1-1.fc34.x86_64. The first crash was in std::__atomic_base<QObjectPrivate::ConnectionData*>::load(std::memory_order), but the traces look similar otherwise. I remember this type of crash happening for me just these two times. -- Backtrace (Reduced): #4 std::__atomic_base<QObjectPrivate::SignalVector*>::store(QObjectPrivate::SignalVector*, std::memory_order) (__m=std::memory_order_relaxed, __p=0x55ce07c03990, this=0x7f4330f8f888 <QQuickBasePositioner::staticMetaObject+8>) at /usr/include/c++/11/bits/atomic_base.h:811 #5 std::atomic<QObjectPrivate::SignalVector*>::store(QObjectPrivate::SignalVector*, std::memory_order) (__m=std::memory_order_relaxed, __p=0x55ce07c03990, this=0x7f4330f8f888 <QQuickBasePositioner::staticMetaObject+8>) at /usr/include/c++/11/atomic:568 #6 QAtomicOps<QObjectPrivate::SignalVector*>::storeRelaxed<QObjectPrivate::SignalVector*>(std::atomic<QObjectPrivate::SignalVector*>&, QObjectPrivate::SignalVector*) (newValue=0x55ce07c03990, _q_value=...) at ../../include/QtCore/../../src/corelib/thread/qatomic_cxx11.h:269 #7 QBasicAtomicPointer<QObjectPrivate::SignalVector>::storeRelaxed(QObjectPrivate::SignalVector*) (newValue=0x55ce07c03990, this=0x7f4330f8f888 <QQuickBasePositioner::staticMetaObject+8>) at ../../include/QtCore/../../src/corelib/thread/qbasicatomic.h:249 #8 QObjectPrivate::ConnectionData::resizeSignalVector(unsigned int) (this=this@entry=0x7f4330f8f880 <QQuickBasePositioner::staticMetaObject>, size=<optimized out>) at kernel/qobject_p.h:308 -- You are receiving this mail because: You are watching all bug changes.
