Bug ID: 428639 Summary: Crash while closing a kconsole window, possibly caused by searching in extremely long scrollback history Product: konsole Version: 20.08.2 Platform: Ubuntu Packages OS: Linux Status: REPORTED Keywords: drkonqi Severity: crash Priority: NOR Component: general Assignee: konsole-de...@kde.org Reporter: rainer+kdeb...@7val.com Target Milestone: --- Application: konsole (20.08.2) Qt Version: 5.14.2 Frameworks Version: 5.74.0 Operating System: Linux 5.8.0-25-generic x86_64 Windowing system: X11 Distribution: Ubuntu 20.10 -- Information about the crash: - What I was doing when the application crashed: To attempt to reproduce https://bugs.kde.org/show_bug.cgi?id=360146: * ran this for a minute or two: while true; do echo -n $RANDOM ============================================================================================================== $RANDOM xx ; done * searched for a random number backwards and forward using the up/down arrows in the search popup repeatedly/randomly * did the same holding down F3 / Shift-F3 * Canceled the while loop using Ctrl+C * Reset+Clear saved lines (Ctrl+Shift+K) and tried again once. Result: the terminal becomes unusable in that it repeatedly and automatically scrolls to random positions in the scrollback buffer, although one can type at the prompt all the way at the bottom. Konsole crashed when closing the window with this session. The crash can be reproduced sometimes. -- Backtrace (Reduced): #5 0x00007f155ccdb94a in Konsole::SearchHistoryTask::executeOnScreenWindow (this=0x560ebdb04d10, session=..., window=...) at /usr/include/x86_64-linux-gnu/qt5/QtCore/qglobal.h:663 #6 0x00007f155ccdbdc2 in Konsole::SearchHistoryTask::execute (this=0x560ebdb04d10) at /usr/include/x86_64-linux-gnu/qt5/QtCore/qmap.h:1281 #7 0x00007f155cced108 in Konsole::SessionController::beginSearch (this=this@entry=0x560ebd995aa0, text=..., direction=direction@entry=Konsole::Enum::ForwardsSearch) at ./src/SessionController.cpp:1455 #8 0x00007f155cced45d in Konsole::SessionController::findPreviousInHistory (this=0x560ebd995aa0) at /usr/include/c++/10/bits/atomic_base.h:420 #9 0x00007f155b696320 in doActivate<false> (sender=0x560ebd32b2a0, signal_index=4, argv=argv@entry=0x7ffcc3e0b5a0) at ../../include/QtCore/../../src/corelib/kernel/qobjectdefs_impl.h:395 Possible duplicates by query: bug 423054, bug 418543, bug 360146, bug 356272, bug 333971.
