Tumbleweed hit the same issues with Qt 6.8.2: https://openqa.opensuse.org/tests/4830727#step/coredump_collect/7 The crashes disappear after reverting two commits: fabian@fvogt-thinkpad:~/qtbase/build> git revert 38f287443c82510719079a254910424b5e510b25 [losgelöster HEAD a64e451d703] Revert "QThread/Unix: move the pthread_key to a file-scope static" 1 file changed, 11 insertions(+), 28 deletions(-) fabian@fvogt-thinkpad:~/qtbase/build> git revert 5acbda4b06ea5f494b56353ff9df60e1a016b55a [losgelöster HEAD a4fd6f6114d] Revert "QThread/Unix: revert to pthread destruction instead of thread_local" Reported upstream as https://bugreports.qt.io/browse/QTBUG-133500 Possibly related to https://bugreports.qt.io/browse/QTBUG-133206 One of the crashing applications is https://invent.kde.org/plasma/kwin/-/blob/master/kconf_update/kwin-6.0-reset-active-mouse-screen.cpp I don't see any global statics.

They are inside KConfig Do note the lack of QCoreApplication implies the Qt state is invalid. I don't know if it helps to have it started, but it should be done anyway. Nicolas, could you confirm that the updated Qt from the 6.8 branch does not crash? Jan Grulich backported the patches suggested by Thiago at https://bugreports.qt.io/browse/QTBUG-133500 https://src.fedoraproject.org/rpms/qt6-qtbase/c/0038317cfdf611eb2d220b9ed196452921b893ae?branch=rawhide. I updated to qt6-qtbase-6.8.2-2.fc42 which had the patches. The kwin and plasmashell kconf update programs didn't crash when I ran them manually in konsole after the update and restarting Plasma 6.2.90. Each program had output lines like QThreadStorage: Thread 0x55c3bb15fc50 exited after QThreadStorage1 destroyed. Thanks. Thanks for the information. I need to understand what is happening, though I can't promise to fix anything. And please add the missing QCoreApplication to those tools. I've compiled kwin-6.0-reset-active-mouse-screen and I can reproduce some crashes. I don't know if it's the same, but I'll investigate. i think i'm also affected by this bug, i can't log in to kde using sddm(the logs look like the ones from the qt-bug), but i can from the tty Operating System: Fedora Linux 41 KDE Plasma Version: 6.3.0 KDE Frameworks Version: 6.10.0 Qt Version: 6.8.2 Kernel Version: 6.12.13-200.fc41.x86_64 (64-bit) Graphics Platform: Wayland Processors: 16 × AMD Ryzen 7 5700U with Radeon Graphics Memory: 7,6 GB of RAM Graphics Processor: AMD Radeon Graphics Manufacturer: LENOVO Product Name: 82MF System Version: IdeaPad 3 15ALC6 (In reply to Vinícius from comment #11) > i think i'm also affected by this bug, i can't log in to kde using sddm(the > logs look like the ones from the qt-bug), but i can from the tty That's definitely unrelated to the Qt bug.

SUMMARY I booted the Fedora Rawhide live image Fedora-KDE-Desktop-Live-Rawhide-20250204.n.0.x86_64.iso in a QEMU/KVM VM in GNOME Boxes in a Fedora 41 KDE installation. Three kwin and plasmashell kconf update programs crashed when Plasma started: /usr/lib64/kconf_update_bin/kwin-6.0-reset-active-mouse-screen, /usr/lib64/kconf_update_bin/plasmashell-6.0-keep-custom-position-of-panels, and /usr/lib64/kconf_update_bin/plasmashell-6.0-keep-default-floating-setting-for-plasma-5-panels. The traces of the 3 crashes looked similar if not the same. The crashes were in std::__atomic_base<QReadWriteLockPrivate*>::load which had a null this pointer which might indicate a null pointer dereference. There was a null this pointer down to QSystemLocaleData::readEnvironment in frame 8 at least Core was generated by `/usr/lib64/kconf_update_bin/kwin-6.0-reset-active-mouse-screen'.

../csu/libc-start.c:360 #57 0x000055f3f396f8f5 in _start () I reproduced these crashes on bare metal with the same image. This image had Qt 6.8.2. These crashes didn't happen in previous Fedora Rawhide KDE live images with Qt 6.8.1. Since much of the traces were in Qt, there might be some problem with Qt 6.8.2 and these programs. Fedora Rawhide was built with a GCC 15 development version which has a problem https://gcc.gnu.org/bugzilla/show_bug.cgi?id=116506 which resulted in crashes of Discover https://bugs.kde.org/show_bug.cgi?id=499100 and plasmashell https://bugs.kde.org/show_bug.cgi?id=499218 STEPS TO REPRODUCE 1. in a Fedora 41 KDE installation, download Fedora Rawhide KDE live image Fedora-KDE-Desktop-Live-Rawhide-20250204.n.0.x86_64.iso from https://kojipkgs.fedoraproject.org//packages/Fedora-KDE-Desktop-Live/Rawhide/20250204.n.0/images/Fedora-KDE-Desktop-Live-Rawhide-20250204.n.0.x86_64.iso 2. install GNOME Boxes if it isn't already with sudo dnf install gnome-boxes 3. Start GNOME Boxes 4. Boot Fedora-KDE-Desktop-Live-Rawhide-20250204.n.0.x86_64.iso in a QEMU/KVM VM in GNOME Boxes with 3D acceleration enabled, 4 GB RAM, UEFI enabled. OBSERVED RESULT Three kwin and plasmashell kconf update programs crashed when Plasma started EXPECTED RESULT No crashes should've happened.
