Bug ID: 486098
Summary: Creating and closing sequentially two QMainWindows
core-dumps with KDE
Classification: Frameworks and Libraries
Product: frameworks-kwidgetsaddons
Version: 6.1.0
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: cf...@kde.org
Reporter: wolf.seif...@web.de
CC: kdelibs-b...@kde.org
Target Milestone: ---
Created attachment 168890
--> https://bugs.kde.org/attachment.cgi?id=168890&action=edit
Reproducer: mainwindows.cpp and CMakeLists.txt
SUMMARY
When creating and closing sequentially two QMainWindows the second one
core-dumps when clicking on it. This only happens for the KDE version, the pure
Qt version works fine.
STEPS TO REPRODUCE
1. Unzip the attached mainwindows.zip
2. $ cmake .
3. $ cmake --build .
4. $ ./mainwindows (close first window and click on second)
Segmentation fault (core dumped)
5. $ LD_LIBRARY_PATH=/home/wolfgang/qt/6.7.0/gcc_64/lib ./mainwindows (works
fine)
OBSERVED RESULT
When clicking on the second mainwindows menubar the application crashes.
When using pure Qt it works as expected.
EXPECTED RESULT
The second mainwindows menubar "Close" should close the mainwindow and quit the
application.
Pure Qt and KDE version should behave the same, only the look & feel may
differ.
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Arch Linux
KDE Plasma Version: 6.0.4
KDE Frameworks Version: 6.1.0
Qt Version: 6.7.0
