Description
When I call libc's `exit` function while my Wacom Tablet is plugged in I receive a Segmentation fault.
Minimal example to reproduce:
#include <QApplication> int main(int argc, char** argv) { QApplication a(argc, argv); exit(0); }
Compiled with `g++ main.cpp -I /usr/include/qt6 -I /usr/include/qt6/QtWidgets -lQt6Core -lQt6Widgets -g` this leads to a Segmentation fault but only when my tablet is plugged in.
Using gdb I get the following backtrace:
Thread 1 "a.out" received signal SIGSEGV, Segmentation fault.
