--- Comment #2 from Matt Fagnani <matt.fagn...@bell.net> --- Created attachment 183839 --> https://bugs.kde.org/attachment.cgi?id=183839&action=edit Valgrind log for RKWard crash I ran RKWard under valgrind and reproduced the crash. There were many uses of uninitialized variables and "Mismatched new/delete size value: 1" involving qtwebengine. The valgrind log at the time of the crash showed an invalid read at the address 0x10. ==5582== Thread 1: ==5582== Invalid read of size 8 ==5582== at 0x1122323E: UnknownInlinedFun (unique_ptr.h:193) ==5582== by 0x1122323E: UnknownInlinedFun (unique_ptr.h:473) ==5582== by 0x1122323E: UnknownInlinedFun (unique_ptr.h:466) ==5582== by 0x1122323E: KXMLGUIFactory::container(QString const&, KXMLGUIClient*, bool) (kxmlguifactory.cpp:450) ==5582== by 0x41AED7F: TwinTable::contextMenu(int, int, QPoint const&) (twintable.cpp:325) ==5582== by 0x13A437B9: call (qobjectdefs_impl.h:461) ==5582== by 0x13A437B9: void doActivate<false>(QObject*, int, void**) (qobject.cpp:4146) ==5582== by 0x41AE835: UnknownInlinedFun (qobjectdefs.h:306) ==5582== by 0x41AE835: UnknownInlinedFun (moc_twintablemember.cpp:162) ==5582== by 0x41AE835: TwinTableMember::handleContextMenuRequest(QPoint const&) (twintablemember.cpp:160) ==5582== by 0x13A437B9: call (qobjectdefs_impl.h:461) ==5582== by 0x13A437B9: void doActivate<false>(QObject*, int, void**) (qobject.cpp:4146) ==5582== by 0x117CF631: activate<void, QPoint> (qobjectdefs.h:306) ==5582== by 0x117CF631: QWidget::customContextMenuRequested(QPoint const&) (moc_qwidget.cpp:603) ==5582== by 0x117F39C1: QWidget::event(QEvent*) (qwidget.cpp:9174) ==5582== by 0x1184D0F5: QFrame::event(QEvent*) (qframe.cpp:521) ==5582== by 0x139D7CA9: QCoreApplicationPrivate::sendThroughObjectEventFilters(QObject*, QEvent*) (qcoreapplication.cpp:1243) ==5582== by 0x1178996E: QApplicationPrivate::notify_helper(QObject*, QEvent*) (qapplication.cpp:3297) ==5582== by 0x117954CA: QApplication::notify(QObject*, QEvent*) (qapplication.cpp:2921) ==5582== by 0x139D7F37: QCoreApplication::notifyInternal2(QObject*, QEvent*) (qcoreapplication.cpp:1106) ==5582== Address 0x10 is not stack'd, malloc'd or (recently) free'd ==5582== ==5582== ==5582== Process terminating with default action of signal 11 (SIGSEGV): dumping core ==5582== at 0x1437709C: __pthread_kill_implementation (pthread_kill.c:44) ==5582== by 0x1431DA7D: raise (raise.c:26) ==5582== by 0x110FF532: KCrash::defaultCrashHandler(int) (in /usr/lib64/libKF6Crash.so.6.16.0) ==5582== by 0x1431DBAF: ???

RKWard crashed with the same type of trace. So the problem can happen with copying and pasting. -- You are receiving this mail because: You are the assignee for the bug.
