Created attachment 118087 [details] Patch to fix segfault in RPi backend at startup When running with the RPi backend, Weston now segfaults at startup on the line: flippipe->clk_id = output->base.compositor->presentation_clock; in `rpi_flippipe_init()`. This is because `output->base.compositor` is NULL. This problem did not exist on 1.8.0, and it looks like it may have been introduced by 954f183e2f. I'm attaching a small patch that ensures that the `compositor` is initialised in `rpi_backend` and the output base, prior to the above function being called. Please consider this patch for inclusion on master as it's currently impossible to run Weston on RPi with this defect.
