Steps to reproduce: 1. Start Qt Creator 2. Press Ctrl+N to create a new project 3. Under Projects, choose Applications 4. Choose the "Qt Quick 2 Application (Built-in Types)" template on the right 5. Press the "Choose..." button to continue 6. On the next screen, give the project a name and press the "Next >" button 7. On the next screen, press the "Next >" button to go for the default Kit Selection 8. Click the "Finish" button to create the project 9. Press F5 to start debugging. The project will build Actual: - When the build successfully finishes, the debugger starts and fails with the following message "The inferior stopped because it received a signal from the Operating System. Signal name: SIGSEGV" Expected: - When the build successfully finishes, the debugger starts normally Notes: - Going to the Projects tab, then choosing the Run configuration and unchecking the "Enable QML" checkbox works around this issue. But obviously then QML cannot be debugged.
