      I am using KDE neon Unstable Edition with qt6-base package version 6.8.2-0zneon+24.04+noble+unstable+build68.

      This crashes since qt 6.8.2 (no crash in qt 6.8.1):

      myqtapp.cpp
      #include <QApplication>
int main(){
	char myqtapp[]{"myqtapp"};
	char platform[]{"-platform"};
	char xcb[]{"xcb"};
	char *argv[4]{myqtapp,platform,xcb,0};
	int argc{3};
	QApplication app(argc,argv);
	exit(0);
}
      compiler command line
      g++ -o myqtapp myqtapp.cpp -I/usr/include/x86_64-linux-gnu/qt6 -I/usr/include/x86_64-linux-gnu/qt6/QtWidgets -lQt6Core -lQt6Widgets
