Yes, the build is having problems with dereferencing the sarea pointers.
in the following code:

  drm_clip_rect_t planeA_rect = { .x1 = sarea->planeA_x, .y1 = sarea->planeA_y,
                                  .x2 = sarea->planeA_x + sarea->planeA_w,
                                  .y2 = sarea->planeA_y + sarea->planeA_h };
  drm_clip_rect_t planeB_rect = { .x1 = sarea->planeB_x, .y1 = sarea->planeB_y,
                                  .x2 = sarea->planeB_x + sarea->planeB_w,
                                  .y2 = sarea->planeB_y + sarea->planeB_h };



My patch did not change that behaviour at all. I wonder if you're
building things correctly, I have no such problem with the sarea being
detected.
