Hello Johannes, thanks for your fast respone. Can you repeat that gdb command with following additional dbgsym packages installed, to complete the backtraces:
libxcb1-dbgsym libqt5gui5-dbgsym libqt5widgets5-dbgsym libqt5gui5-dbgsym libqt5dbus5-dbgsym libqt5core5a-dbgsym libglib2.0-0-dbgsym libgl1-mesa-dri-dbgsym libqt5qml5-dbgsym As an distant observer I cannot say if the "clang code model" thing deserves its own separate bug, has to be better decided by the package maintainers... If it shows up just sometimes you probably can describe your cpu and number of cores? Is it hanging too, if you start qtcreator with following command: taskset -c 0 qtcreator Kind regards, Bernhard
