Qt for Device Creation 5.11.0 Emulator
Description
Crash is reproducible with Device Creation emulator running an empty QML example generated with QtCreator (Qt Quick Application - Empty).
Crash also does not occur if running example through debugger from QtCreator. Running gdb directly in the VM image, gives backtrace:
